I'll be doing 210km MQSM for the first time this year, and while I've been riding through most of the winter, I have missed a couple of months to illness, and expect to be taking it relatively slow.
I don't know anyone else riding, so my plan is basically as suggested. To find some other people who are travelling at a pace I'm comfortable with and seeing if we can work together to maintain slightly better pace with slightly less effort.
Failing that it's nice to find a big strong rider and shamelessly draft in their slipstream.
I'll be the overweight, grey beared guy in the event jersey riding the CX bike with marathon plus tires.
Stop sign? Fixie don’t care.
