C2C Route

Which bike?

Q: I am an experienced [amateur] road/time trial rider wanting a different challenge for this summer. My question:  Should I use Wilier carbon road bike 39/53 and 11/26 with schwalbe marathon plus 25s, or Planet X Uncle John cyclocross with flat bars, compact chainset and 11/28 with the same tyres.  I’m planning on a two-day c2c so want to balance comfort with pace.
Thanks. Paul

A: I’d go with the road bike if you’re wanting a fast time or the Planet X for comfort. Hard one to call. On balance, I’d opt for the latter. I’m happy to throw this one open to readers.
