Ok, so I searched, and searched, and I just cannot find the answer to my question, so here goes...
How long on a trainer equals time outside on the bike. When you are outside, there are flats, coasting down hills, tailwinds, headwinds, etc, etc, etc. I just used my Minoura Mag trainer last night for the first time for 25 minutes and it just about killed me. I had it on the next to lowest setting, but I was in my highest gear. I was drenched in sweat and my legs were like Jello when I got off. I usually do an hour and fifteen minute commute in to work at least 3 times a week during the better weather, so shouldn't I be able to handle a half hour on the trainer?
How long on the trainer equals an hour or so ride outside, and how do you figure out the settings? I guess trial and error, but it seems like there has to be some easier way to figure out how long to stay on the thing.
Thanks for any help anyone can offer.
