I've gone a couple times down the Provo River Trail. Once all the way down to the Utah Lake, and another time HOPING to head up towards the canyon, but the trail stops at the Motion Picture Studios. (lame)
Then yesterday I had some extra time in the morning, so I decided to try something a little more ambitious. My barber (apparently EVERYONE is a mountain biker) suggested I try a part of the Bonneville shoreline trail that starts in north Orem (by the cemetery) and heads up towards Pleasant Grove. I didn't do so bad, but the 4.5 miles took me a LOT longer than I expected! The thing that was great is that there were a lot more ups and downs (instead of one constant climb like the last offroad trail I tried) so I would get a good work out, then breath a little while I went downhill.
The interesting thing about the trail (which I found at utahmountainbiking.com) is that it climbs 650 feet over the first three and half miles or so, and then goes back down nearly all 650 in the last mile. The whole time I'm going down (scared to death and riding my brakes half the time....) I'm thinking "I'm gonna' have to ride back up this!" Fortunately, the map provides an option for a city street return.
I must have missed my turn, because I ended up being WAY down in the middle of Pleasant Grove and having to wander my way back up towards the cemetery in Orem. I rode by Jill W.'s house, but decided against riding all the way up that hill to say hi, plus I had a lesson to teach soon and had to get home.
All in all, it was a fun ride! I think I'll try it again! AFTER looking at a map.
