Yeah, I missed the last F11/10 to do the ECCA100. There's another later in the year but it's post TCR so probably no point for me. Might have to wait until next year.
F2/10D looks interesting. Has anyone raced it before?
F2D/10 is fast, and can have reasonable traffic levels if everyone in Cambourne is going shopping in Cambridge. My 10 mile PB is from the F2D/10, and that's after having riden the E2/10 twice.
F11/10 has a gift hill half way through. And I think the F2D/10 could be pretty fast - very flat and good road, but prob lacking traffic. https://www.cyclingtimetrials.org.uk/race-details/11425
