Twice a week I ride intervals on the trainer. I can get the interval session done in about 60 minutes including warm up & cool down, in which case I need to get up around 5:15am. Or I can extend the non-interval portion of the trainer ride, for a total ride time of 90 min and then I need to get up around 4:45 am. With the 60 min interval session, I can get 8hrs sleep, with the 90 min, it will be about 7.5hrs sleep. I'm pretty ok with either amt of sleep.

On weekends I am riding about 120-130 miles on the road training for a century ride in a few weeks.

I was doing 90 min sessions but now Im wondering how much I'm really getting out of that extra 30 min. I enjoy it & totally rock out to my tunes. But now I'm starting to think the sleep might be more beneficial. Not because I'm tired, just because it's good for training too.

Thoughts?
