No longer a stoodent I'm afraid. Looks the 10 is being hosted by OUCC again, which means the 10 will probably be H10/17r and the 25 by CUCC, who used E33/25 last time. H10/17r is fine on fixed, I was on 100" in 2013, bit of a drag up to the turn but no major hills. Never ridden the E33/25, but it looks fine as well.
