They're both in cheyenne. The actual pool time is from 6-7 both days. I usually leave fort collins at about 5 or 5:30, then meet up with nathan and carpool from his house.
I know it's kind of a lot of driving, given that the sessions are only an hour long, but this is what I've found so far, and I kind of like this pool. The lifeguards are a lot more friendly than the csu ones were (apparently the trick is to hire high schoolers instead of college students) and the pool is deep enough, unlike the raintree pool (csu sessions last year). I suspect that there are also some sessions in boulder or something, but I haven't looked into it.
