Brogborough '10' 24th July 2024

Thirteen riders entered this club event on the F15/10 Brogborough course. I'd been feeling pretty optimistic after my 21:56 in the VTTA '10' the other weekend! For the record, I've been following a TrainerRoad high volume 40k masters training programme - at least as best I can given various things impacting on my training. I don't do specific FTP tests as I prefer to use the TrainerRoad AI FTP estimation. I also track my training using intervals.icu which offers its own FTP estimate, usually a few watts lower than the TrainerRoad AI FTP estimate. I guess the true value lies somewhere between them.

On the evening of the event, we had a 13mph tailwind for the outbound leg, and a corresponding headwind on the way back to the finish. I'd chosen to ride the P5, and felt pretty good in my usual high gear with the tailwind. I'd noted good speeds whenever I looked at the Garmin - usually around 30mph. Of course things were a little harder on the way back, and while the power and heart rate went up, my speed and gearing went down!

I crossed the line with 22:58 showing on the Garmin, but unfortunately in reality I'd just tipped past the 23 minute mark! On looking at the data, I had a normalised power of 248W. I'm seeing a gradual increase in power levels in recent 10 mile time trials, which is encouraging as I often feel I'm fighting back the impact of passing years!

Later that evening I ran the TrainerRoad AI FTP assessment. This is based on all activities recorded in TrainerRoad, so I think it includes road events. Over the last 6 weeks or so, my FTP estimate seems to have bumped up by 5W to 246W. Not too much I guess but it's the right direction at least. The intervals.icu estimated FTP rose slightly to 237W.
