The rain was just starting as I left work to ride down to that start of this club event. It was also rather twitchy riding in blustery wind, so the signs weren't great! When I got down to sign on, I found a clutch of riders sheltering from the rain in the lee of Tony's car discussing whether or not we should ride. Some did not, but a core of nutters (including me) decided we'd go ahead.By the time we lined up at the start, Anthony B. had decided that having ridden round the course he wouldn't start - he reported the roundabouts may be a bit slippy. Another rider joined him in not starting, leaving the rest of us entertaining all sorts of doubt. However, at the appropriate time, I found myself launching off up the road in the a stiff and blustery wind. This had the effect of making my front wheel really twitchy. Nevertheless, I pressed on to the first roundabout which I negotiated with some care, given Anthony's warnings - and the fact this one's ridiculously potholed. For much of the rest of the event, I was mostly either whizzing along with a bit of wind assistance or grovelling along trying to control the bike.The only truly alarming moment came when I was crossing the last roundabout (i.e. the first one in reverse) and I hit a pothole. This threw my front wheel to such an extent that I thought I'd bought it! Somehow I managed to regain control and made a final effort to the finish. Third place with a paltry 23:50.Here's the Garmin trace, and the full results at the NBRC website.

This was only my third '25' of the season, and on the F1B/25, the somewhat less flat version of the F1. This course heads south from Tempsford to turn at the Baldock interchange, just where the A1 changes into the A1(M).A nice enough morning heading out to the event, but by the time we reached the race HQ at Tempsford hall, the skies had clouded over and light had fallen a bit. Fortunately, by the time we started, things had improved a fair bit. As regards the event itself, it was marred somewhat by a stiff sidewind, which at one point threatened to overturn me! I had a pretty clear run through all the roundabouts.There was an annoying diesel spill at the miniroundabout near the start, but I don't think it caused any trouble with the riders.All in all an uneventful ride - I finished in 59:49, and went home to feed Tony blueberry pancakes!Here's the Garmin trace.

Can anyone explain why tubeless tyres are such an advantage for road bicycles?  The push towards tubeless tyres is exemplified by this review of Easton tubeless aero wheels at Velonews. Early in the review, we see this:

Cars, motorcycles, and mountain bikes use tubeless clincher-style tires almost exclusively. Road bikes are one of the few wheeled vehicles that still rely on tubes to hold air. And tubes go flat.A clincher rim with a solid spoke bed (and a few design tweaks to help the tire bead seat against the rim) is capable of running tubeless with minimal changes. A special valve, a tubeless-specific tire, and a little sealant are all that is required. Nipples thread into the inner diameter of the rim. And if anything goes wrong with the tubeless setup, these wheels can be used as standard clinchers as well.The EC90 Aero 55 clincher was designed to run tubeless without the additional headache and pieces involved in converting a standard clincher. More shallow aluminum (read: not aero) road rims wheels are adopting this construction, and the EC90 Aero 55 is the first aero wheel to do so. Tubeless specific tires are thicker than standard tires, so rolling resistance is a factor when deciding to use a tube or tubeless setup for a race, although practically eliminating flats is a very appealing advantage.While tubeless road wheels haven’t yet exploded as they did for mountain bikes, nearly 30 tubeless tires are currently available and the number is growing.

I really wasn't aware that mountain bikes almost exclusively use tubeless tyres - is this an American thing? Apparently the fact that tubes puncture is a reason to go tubeless - but to puncture a tube, the tyre has to be punctured first. And it seems as though the response to puncturing a tubeless tyre is to put a tube in, and that'll presumably be mucky with the sealant that's needed!  Oh and only a few tyres are available, and they tend to have higher rolling resistance.I can't help feeling that tubeless road tyres are a solution in desperate need of a problem! On the other hand, I presume Easton figure there's a market out there for high spec tubeless wheelsets.

Rather a nice evening for a time trial - sunny, but not too hot, and with only a fairly gentle wind. Unfortunately I felt pretty grotty and found the ride quite tough!I set off from the start feeling reasonably OK, made it through Beachampton OK, but fell apart a bit as rode up the climb to Nash. I had the added impetus of knowing my colleague Katja, on her second race on her new TT bike, was starting a minute behind me! I was unable to read my bike computer, due to sunglasses an age-related vision issues, so mostly I was riding on feel. This wasn't really good enough, as all I was aware of was feeling really rubbish as my speed dropped away on the climb to Nash. Once up there, things got a fair bit better.I was doing a good job staying on the tri-bars round the bends and corners. Well, mostly. I did descend well from Nash through Beachampton, but lost a bit of speed on the twists and turns over the last few miles to the finish.The event, overall, was a bit of a let-down after last week's ride at Astwood. I finished fairly low in the pecking order with 28:32. Full results at the NBRC website.Tony and Amy were out on the tandem to see the race: I rode back part of the way home with them (they did seem to be going rather fast for my tired legs).

I was quite pleased that the current heatwave abated slightly for this evening event on the Astwood circuit. As usual, I lined up at the start yawning widely and proclaiming that I was too tired and hungry to do a decent ride.A few minutes before I was due to start, I had to nip into a field for a nature break. Unfortunately, upon emerging I found my Speedplay cleats had clogged up with mud and I had to spend some time poking the mud out with a stick retrieved from the verge. This was rather disconcerting as even after I dug the mud out I found that unclipping from the pedals was most erratic.Anyhow, I started as number 4 and pretty soon after starting, found the outward leg to Chicheley rather twitchy and difficult due to the wind. Once round the turn things got easier, and I began to entertain hopes of a sub-24 minute ride. By this time, I'd caught one rider and had a second in my sights. I redoubled my efforts and pressed on to catch the second rider. In these evening events, I find I'm unable to read the smaller numbers on my bike computer (a combination of vibration, low light, and needing reading glasses). I was able to make out the elapsed time, and I figured I'd need to put in a serious effort.By the time I reached the final descent before the climb to the finish I could see the last of the riders in front of me, and I threw everything into the effort needed to catch him. This I managed, just before the finish, with a final effort that saw my heart rate reach 203bpm! Gagging and gasping, I slumped to a standstill, hoping against hope I'd got under 24 minutes...and when the results were sorted, I found I'd done a 24:00 for third place.I was reasonably pleased with that result, which may just be showing some signs of a recovery of form. Here are the results and the Garmin trace. 

We had a weather forecast of thunder and lightning for this event. On the day, however, it was another very hot afternoon, that mostly made me want to loaf around instead of exert myself! Tony came round to my place, and we rode over to the race HQ at Lidlington. When we got there, we were told by a timekeeper that roadworks on the course had necessitated a last minute change to a course thought to be about 7 miles. Instead of turning at the second roundabout (Wootton), we'd turn at the first roundabout (Marston Moretaine), retrace to the foot of the hill then turn left along the wonderfully named Sheeptick End, finishing just before Lidlington level crossing. Supposedly, this was about 7 miles (actually I made it about 6.5 miles). Another amusing factor was that this was a 'flying ant day', when all the new queen ants were emerging. I could hear these beasts bounding off my aero helmet, and see dragonflies and swifts zooming around eating them!Off to the start, and I did my best to warm up. I cruised up and down Sheeptick End, until I was confident I knew where the finish was. This section needed a bit of care, as there are several fairly sharp bends with large parked vehicles such as camper vans. The start was a little alarming, as the pusher off seemed to be having a little difficulty holding my bike, but soon enough I shot off down the starting hill. The outward leg wasn't too bad, and I was holding a decent pace to the turn. Unfortunately, the turn was affected by a line of half a dozen cars and their drivers seemed to be a little alarmed by the rider ahead of me that I was about to catch. After negotiating my way through that, I passed the rider and set off back along the course, dodging potholes as I went. The surface of the road seems to be deteriorating quite quickly.The return leg wasn't so quick, and I was quite relieved to reach the little rise before turning off onto Sheeptick End. This lane was quite quick at times, quite slow at others, but with a rather rough road surface. I eventually crossed the line in 15:02. The race was over, seemingly not much more than a warmup!Here is the Garmin trace.

This was another warm and humid evening, with only a gentle breeze to bother the riders. We had a reasonable turnout of 14 solo riders and one tandem crew. I was what you might call well-rested, having been off the bike for a few days because of work commitments, so I was keen to gauge my fitness against my peers. I ended up as the penultimate starter, with only Tony P. behind me. So obviously, the fear was that he'd catch me embarrassingly early in the event.My start was pretty uneventful, and was pretty quick. Approaching the first roundabout, I was aware of a car coming up behind me, and took a conservative line through the roundabout. Unfortunately, this really slowed me down as I had to negotiate the huge potholes somewhat carefully! From there on, things did get better. As usual, the climb up to the main dual carriageway was a bit slow - I think the wind direction had a bit to do with that. Onto the dual carriageway, and my initial speed was around 30mph, which was encouraging. Unfortunately, this soon dropped away as the gradient flattened and the breeze took its toll. I began to get a little worried! Coming out of the turn, I could see Tony, who seemed to have gained rather more on me than I had hoped.Once round the turn, things got a bit quicker, and I felt a bit more up for it. I had no real issues negotiating the last roundabout crossings, and finished in 23:20. This was somewhat slower than my last ride on the course, but as far as I could see from looking at the results, everyone seemed to have gone a bit slower in comparison. The traffic levels seemed OK this evening, but several riders said they'd found that cars had been passing a bit close - this was certainly my experience. Nothing dangerous, mind, but it does remind us to keep our eyes open!Here's the Garmin trace for the event.On Saturday, I'm off to ride the Norlond '10' on the F15/10. Thunderstorms are forecast, which may liven things up a bit!

I think this is only the second time this year that I've raced on this course, owing to illness, injury and pressure of work (it takes a while to ride over from work, so late meetings are quite disruptive). This event was true to form, my back pain had returned, and I only managed to make the event because a new colleague at work wanted to ride and offered me a lift to the event. The lengthy period of hot and sunny weather continued, with the event being run on a hot and sunny evening. There was a rising head wind for the closing section, but really, the conditions were pretty good.I was quite a late starter, and found I was feeling pretty good as I set off. By the time I reached Beachampton I thought I was going OK - indeed I only felt like I was in any real difficulty at the steepest part of the climb up to Nash. On the other hand, this is far from my favourite course, and it's particularly unforgiving for riders who are a little overweight (as I am) or who have a niggly sore back (as I did)! I could see most of the riders on their return leg as I headed out - they were whizzing back down the hill looking for the most part like they were enjoying themselves.Riding through Nash, I could see there were kids on bikes in a schoolyard. After I turned (no issues with traffic or farm animals), I was concerned to see people, including the kids, wobbling about in the road. This brought back memories of the Icknield '10' on the Brogborough course (F15/10) last September, when two small kids caused me to come off at speed. On this occasion, everyone kept their line and I safely negotiated the twisty road through Nash and started the descent. This was quite quick, and I was still feeling good as I passed through Beachampton. Over the rise after Beachampton, and into the last few miles of twisty lanes and I felt I was flagging a bit. Indeed, I crossed the line with 28:18. Not bad I suppose, given my recent performances, but I'd have liked to do a '27'! Full results here.  

This was a blisteringly hot day - according to Tony's car's thermometer it was 29 degrees (my Garmin registered a maximum of 33 degrees during my ride) - and with a stiff old breeze from the north that greatly exceeded the 7mph draft that was forecast. It was my first outing on the E2/25 for a year or so.Driving out there, it was clear that the conditions were going to be 'interesting', due mostly to the heat, but also the wind. We collected our numbers from the HQ and retired to a lane near the start. Tony was off slightly more than an hour before me, and I found what little shelter I could beside a hedge and waited. After a while I rode up and down the lane, but it was so-o-o-o hot! By the time I rode off to the start, I'd drunk almost everything I'd brought (clearly insufficient!) and eaten a banana as I was feeling a bit hungry. I reached the start line a bit early and waited in the shade of a tree while talking to one of the women riders (I was starting three minutes after the women in the race). Passing riders who'd already finished observed that it was pretty tough on the return leg.The start was pretty straightforward, though I always get nervous when the pusher-off actually pushes me off, as it always feels like I'm going to depart in an unfortunate direction! But everything was OK as I zoomed off down the sliproad onto the A14. The breeze instantly had its effect, and indeed the outward leg was pretty quick all the way. Coming out of the turn, I was caught by #80 for three minutes, then at the bottom of the slip road by #78 for one minute. No-one else passed me, though I did catch some of the women riders.I found the nagging head wind a bit tough, especially on the slight uphill gradients (the course is actually really flat for the most part). I was also getting very thirsty, with what little saliva I could muster gluing my mouth up! So it was something of a relief to see the finish line looming! I finished in 57:02, which isn't too bad given my season so far.After the race, we returned home for home-made pizza and Leffe, which rounded off a hot, sticky and reasonably successful afternoon out.Stats-wise, I spent most of the race at rather a high pulse rate, often in excess of 190bpm. I think this reflected both the temperature and the effort, though the power recorded by the Powertap wheel was rather lower than I'd expected. All these data and more in the Garmin trace! 

One of the main reasons for buying a new tandem was an improvement in transportation. Not, I add, in transporting us and our luggage but in transporting the tandem by car. In the UK it's pretty much impossible to travel by train with a tandem, so each time we plan a cycle tour, we need to allow for getting the tandem to the starting point using our car.
