The advice I offered was how I do all rides with my current lack of fitness. Hold something in reserve for when it has to be used. Why stay with the fast boys when there are hills coming up? Take the hills at a pace that will get you up and once the hard part of the ride is done- Then push a bit harder.
I follow this advice on all my rides except although I get the hard bit done with energy left--I no longer push harder afterwards.
But looked at this ride on elevation and those hills are not in the best place on a century ride and they follow on from each other. Just the sort of ride where exuberance could take over from sanity and you could burn out too early.
As Mobile found out-Experience and sensible riding pays on this sort of ride and Mobile proved it.
Well done.
