I ride in Utah. I'm by no means a racer. I could never do that, especially on a Mt. Bike. I'd kill myself for sure. LOL!
I live in the Salt Lake area and there are tons of trails here. I've riden in Moab (3 hrs away) twice so far. Normally I ride anywhere from 6 to 23 mile trails here, but these trails aren't as tough (I can't figure out why really) as the Moab trails I've been on, I went on slick rock and that's a hard one to, but fun. I did a 23 mile ride a couple weeks ago here and it only took 2 1/2 hrs. compared to the Porky Pine rim trail in Moab taking me 4 hrs. for almost the same amount of miles.
I don't ride as much as I should. But my husband rides the 23 mile trail here at least 4 times a week. He does it in 1 hr. 38 min.(I hate him LOL!) I add on an hour to his time, so I don't go as much. I hate to drag him down. LOL!
Lately, I've just been riding a hill climb almost every morning, that only takes me 1/2 hr. but it's steep and a good one and helps keep my legs in cond. for climbing on longer rides.
Anyways, the trails are so fun. My husband loves to climb uphill and I love to go downhill. But we do manage to enjoy it together, most of the time. But, There have been moments.}(
