I'd also like to do the Mickelson Trail. I live in SD, but on the otherside of the state. I don't know if I want to do the full trail in one day (there's an organized ride toward the beginning of the season) or do the 3 day version so that I can enjoy the scenery (organized tour at the end) more. However, I think a two day version would be about perfect too.
Anyway, I started riding at the end of July 05. I got a hybrid then. Last season I got my road bike, but got a late start due to a broken arm. I still managed my first century in an MS150 tour.
I hope to do the Tour de Kota, I realized last year that I'd have to start riding earlier in order to do it comfortably. I will do the MS150 again from Sioux Falls. And if things go REALLY well... maybe I'll try the W.R.A.T.H ride (Weekend Ride Around the Hills: the Rapid City MS150... Though that still seems to be brutal for my rookie legs). We'll see how hilly this year's Tour de Kota is.
I also want to keep running. I'm knocking at 4 miles now. Just under 12 min/miles. Still slow, so I'd like to get a bit better at that just for myself.
