He's raced a dozen times this year. I've done 2x2hr rides around Hillingdon. Maybe time to reintroduce some specificity and get some events in beforehand.
Imagine the aero testing I could fit in if I made it to retirement age...
The trend is for aeroz to improve faster than the VTTA curves go the other way, so it will be easier for you to break 300 miles when you are 60. So why bother next year?
You can always come back later - David Shepherd is 60 🙂
