Just going to put this out there as I'm not really sure I know the answer... It's more training related so kinda aiming this at
@BennyC as he's been quite quiet on here recently - but equally open to all!
With Zwift, I've used the Tour of Zwift and Racing quite a bit this winter/year to 'get myself back on track', without many/any outside rides around commuting. I've followed no plan (as usual!) and being time pressured have just fitted these rides in whenever I can. The way I've ridden these I've got quite used to riding at threshold for an hour (sometimes more). I know this isn't sustainable or repeatable on the road.
Now the weather is getting a bit better (jinxing it now), the chance of me making one of the local group rides is increasing, what else should I be looking at doing to balance out my training a little - rather than just hammering out threshold rides?
Or is hammering out an hour of threshold fairly good for a fitness perspective, so when I do a couple of hours group riding on the road at tempo I'm not going to be dropped hard!
