For the third weekend in a row, I lined up for one of the CTT winter series. This time we were on three laps of the Richmond Fan Flats course. I made sure to have a look at the course, which was good because there was a significant lean-in before the first of the three laps. In fact, I used the warmup to ride round the lead-in and first lap.

As you'd expect from the name, it's a pretty flat course though perhaps a bit more undulating than Tempus Fugit used for the first event. Despite feeling quite good for this event, it didn't go quite according to plan.

After last week's Zwift time trial which was held on a pretty much pan-flat course, I was hoping for some improvement. Of course I rode last week's event after a week away with limited training and the day after a horrible journey home, which I think one must bear in mind. Also, I muffed the last few km, when I thought I'd finished with a couple of km still to go.

This week's time trial was on a fairly hilly course: Watopia's Triple Twist. 24.3km with about 201m total ascent. I was hoping that the undulations in this route, together with the two climbs might make the riding better resemble riding in real life than last week's route. And overall, I think it did. I still find holding consistent power rather harder in Zwift than on the road.

It's that time of year when Zwift riding is pre-eminent in the weekly schedule - and the CTT have set up a Winter Series of time trials on Zwift, Unlike the VTTA series I've ridden for the last couple of winters, they've selected a range of courses from flat to hilly, which promises to be a bit more interesting that riding the super flat Tempus Fugit course week in, week out as the VTTA have used.

That said, the first event was indeed on Tempus Fugit, but with a different finish point than the VTTA used last year, at 20km. Approaching this ride, I really wasn't sure how ready i was for it: after the best part of a week away from home with real disruption to my training routine and with a rather stressful journey home the day prior, most of my rHR and HRV metrics were a bit off kilter.

I have a number of wheels which have Shimano compatible 8 to 10 speed freehub bodies. Two of these wheels are intended for use in a time trial bike with 11-speed systems, and one is the new rear wheel bought for the Longstaff tandem (LINK).  Accordingly I’ve spent a bit of time figuring out to upgrade these wheels to 11 speed.

Freehubs designed for 8 to 10 speed cassettes are very slightly shorted than those designed for 11 speed cassettes. They can fit standard Shimano cassettes from 7 to 10 speed, requiring a spacer in some cases. You can fit 11 speed cassettes if you drop out one of the cogs. This might not be the best solution for a racing wheel, but works fine if you’re not focussing on smallest cogs.

Another bout of modifications to our summer tandem, resulting in a rather mixed transmission: 11-speed Shimano cassette (reduced to 10-speed), Shimano 105 levers and rear mech, a 1990s Campagnolo tandem chainset and triple front mech, KMC chain, new Campagnolo BBs.

Two Bossard Wheelers 10 mile time trials were added to the calendar recently, both on the F15/10 - probably the closest time trial course to where I live. I entered both of them (4th and 11th October).

The first was abandoned in the face of Storm Amy.

Together with my regular 2-up partner Gerry, I rode the famous Duo Normand time trial every year from 2003 to 2019, bar one. In 2020, it was absent from the calendar owing to the Covid-19 pandemic. It didn't reappear in the following years, and most of us thought it had gone for good. But in mid-2025, it was announced that it would return on 21st September 2025, on a revised course of 40km. With the announcement coming quite late in the year, fewer teams than in the past were able to enter, with very few from the UK. But despite advancing years and dubious fitness, Team Grumpy decided to cross the Channel for another ride in the this splendid event. We were not disappointed.

In September 2003 I first rode the Duo Normand, a well-established 2-up team time trial in the Normandy countryside around Marigny. My teammate for that, and every subsequent Duo Normand ride, was my regular 2-up partner. We semi-seriously style ourselves Team Grumpy, and we have a Team Grumpy website. We rode the Duo Normand every year from 2003 to 2019, except for one year. The high point was our victory in the Corporatif category in 2010, but since then age has brought with it diminishing returns.

Team Grumpy on the way to victory in the 2010 Duo Normand, soundtracked by a cacophony of infants and church bells, but total indifference from the crowd.

I switched to Athletica.ai as my preferred training platform pretty much a year ago, and aside from a brief absence from the platform (after which I had to start pretty much from scratch) I’ve found it pretty good on the whole. Athletica seems to be well-rooted in the science of training, with a significant reliance on HIIT workouts. A typical workout schedule for me generally has one HIIT workout each week (shown below via intervals.icu below, click the image to enlarge).

This was the final event in our series of evening club events, and attracted 13 entries (though one didn’t start owing to illness. Through the day we’d had some spectacular thunderstorms and extremely blustery conditions with gusts of up to 48mph. Clearly not ideal, but at least by the time we started the event things had calmed down, and despite there being several heavy showers tracking around Cranfield, I think all the riders completed the course without getting wet.

For my part, I found the outward leg down to Newport Pagnell rather tough and the still rather gusty wind made it impossible to keep on the aero extensions. I was caught at the turn for a minute by a fast rider on a road bike. Things were a bit better on the return leg and I was making better progress to the finish. I ended up in third place with 25:52, good enough for second on veteran standard.

This evening ’10’ came after a fortnight of dealing with a right leg injury (bizarrely incurred while mounting the tandem) and a longer period of family related stress, both significantly denting my training, all mixed in with a few hospital appointments.

Last week, I rode a club event on the Cranfield course, which I won with a narrow margin, but at some cost to my right leg’s recovery. Frankly I didn’t really pull out a strong performance that evening. So I was keen to see how I was going via this evening’s event.

This review really focusses on  the optical HR data collection with my newly purchased Polar Vantage V3 watch.

Last autumn, I bought a Garmin Vivoactive 5 watch, largely to collect data that was then pulled in by Athletica.ai, such as sleep, resting HR and HRV. Watches have never really been a maor part of my sports data collection - because I almost explusively train on a bike, I generally collect data via a Garmin Edge bike computer (currently an 840), or via trainer software such as Zwift. So, why go back to Polar, specifically the Vantage V3?

I noticed the other day, via the GP Lama YouTube channel that the latest firmware update for the Garmin/Tacx Neo 3M trainer (and, I think, the version 2 and 2T Neo trainers) enables virtual shifting on the Zwift platform.

I run Zwift on an AppleTV in my garage using a Tacx Neo 3M trainer, and I experience some issues. Firstly, the AppleTV bluetooth remote buttons are gradually breaking, presumably an accretion of sweat damage. Replacements aren’t cheap (and might just go the same way). Secondly, I often have a bit of trouble with jumping gears while training, particularly in intense intervals.

I was rather pleased to have more moderate weather for this event - rather than hitting the 30 degree mark, we were in the low 20s. I looked at the weather and decided it was sufficiently blustery that I needed to take care with my front wheel choice. In the end I think that my decision to ride the P3C with its Hed trispokes was wise. In any case, I want to get some rides on on it to do any fine-tuning before the Duo Normand (if they ever open entries).

The opening section along the bumpy University Way ends with a left turn onto the road to North Crawley and Newport Pagnell (we turn just after the 'civic amenity site'. Much of this leg is downhill, but the expected speed didn't really materialise because of the haed wind. Additionally it was quite difficult to see the many road defects in the evening sun. This particularly bad as you approach North Crawley.

This event was moved from the scheduled Brogborough course owing to roadworks. I decided to try the backup Cervelo P3C TT bike for this event, largely because I was interested to see if my recently resolved foot pain issue might move my L-R balance back closer to 50:50. The bike has Favero Assioma power meter pedals and venerable Hed H3 trispokes front and rear. I think it looks the part...here I am just after turning left onto the main road.

I have this set up with SRAM 11-speed Red eTap - there are gear switches on the base bar but I'm using the blip box as switches while on the aero extensions - you can see it by my right hand in the photo. This works well, but I'm going to try and sort out a more rigid way of affixing the blip box. 

A very warm morning for this open event. While it was held on the Astwood circuit, the start and finish were in different locations and I never do well on this version. I finished in 24:53 in the middle of the field. I think having the hardest climb on the course after a mile and then having to race to a T-Junction and along Astwood Hight Street just slows me down a bit.

Full results via CTT.

We had a warm evening for this club '10' on the Astwood course. I was somewhat concerned by a hospital visit the day before, which preyed on my mind through this event.

The warmth was a bit oppressive, but the first section down to Chicheley and the first turn was fairly quick. Once round that turn, I found it a bit harder to keep the power up. Whether that was a lack of focus or the tail wind (or maybe both), I'm not sure. In any case I felt decidedly lacking.

This time trial didn't go according to plan! We did have quite a nice evening - warm but maybe a bit windy out there on the dual carriageway section. Issues began with a missing magnet on my helmet, which meant my visor wouldn't stay attached. I rode with my Bolle sunglasses, which meant I spent a lot of time peering over the top of the frame - plus my helmet was rendered quite non-aero! 

Also the traffic flow out on the course seemed a little odd. This was noticed by a number of other riders, and meant I got a bit held up at three of the roundabouts.

I have long since stopped blogging my progress through the 1001 Albums You Must Hear Before You Die. I’m doing this through a web site which serves up an album each morning, and an associated plugin for the music server that I use (Lyrion Music Server, or LMS). The plugin links to the album via Qobuz, which I subscribe to. In fact, I can only recall a single album that the plugin couldn’t find, and I ended up playing it on YouTube.

I recently found I’d played half of the albums on the list, so I thought maybe an update was worthwhile.

Another Wednesday, another club ’10’. This time we were back on my favourite course, Astwood, and as usual I prepared the signing on and timing sheets for Dick to use. I’d also reverted to my deep rim front wheel as I didn’t think the wind would too much  for me to handle the wheel.

When I arrived up at the meeting point in Astwood, I discovered to my annoyance that the paperwork had fallen out of my pocket en route. That was easily remedied using Dick’s blank signing on sheets, so no real problem.
