my club hosted a road race last weekend and to cut a long story short i split the group by sitting up, then chased the leaders down who were all apart of my club and then i was dropped back to the chassing group.
there were 4 of us again from the same club and we started to organise ourselves to chase them(the leading 3) down but we had a fresh member of another club with us ?
i said dont chase them as we have a 1,2 and 3 for the race, let him do the work and chase.
this is the question?
at club level do you think this is appropriate or should you just ride your own race ?
its happened to me in the past with lead out's and being boxed in, but now i feel a little guilty.
