I've never really trained, I just used to ride and race frequently.
I don't watch the HR at all during the race, I'm just reviewing it afterwards as I do after a ride.
Memory of previous (limited) ability is a problem, especially since the last stint where I didn't ride at all for a few years and probably lost most of my base.
I think I've already clarified that I don't expect to be top 10 anymore, but I would like to feel like I'm riding competively within my race within a race wherever in the field that might be. But yes, as I've acknowledged, I need to take some steps if I hope to realise that desire.
It should be interesting, and I guess I'm fortunate that I can afford now to do something about it when previously I didn't even really have to try.
I've also bought a trail bike recently and a load of new more technical trails have just gone into the area I usually ride.
