75 was fine. I had plenty of daylight to cover it without getting into a rush. I didn't have to go into oxygen debt to meet my schedule and I had time to stop, look, eat, and just cruise along.

But, it's very flat around here. There were a few hills, but nothing to brag about. I don't know how far I could go given a truly hilly or mountainous region.

I just looked at the weather for that first day. Early in the day the winds were about 10mph, progressing about to about 22mph, with gusts up to about 30mph. It felt challenging, but I don't know how that compares to riding in the mountains. Probably not close.
