Keep yer fingers crossed - weather is looking Ok for the MGST at the moment - partly cloudy and 68.
I indicated my intent to do the 45-mile ride, but considering the 27 miles I did last Saturday is the most I've done in one shot all season, I'm not sure I'm ready for the 45. On the other hand, the 27 had lots of little hills, and I understand MGST is pretty flat. I'm hoping to get a quick 20 in tomorrow after work, so we'll see how I feel about things on Sunday.
