16 miles, out and back, no hiding on the A70. Starting in Cumnock and turning at Muirkirk, this is a straightforward test of pace and nerve - lumpy enough to hurt, long enough to make you regret going out too hard! One rider, one road, one number on the results sheet. Always worth giving it a hard bash to test yourself. This is the late season instance of the TT - the early season one is in April.
