After the kickoff of the season last weekend in Fresno, it's the Sierra's turn with TBF Racing MTB Challenge #1. The festivities start at 9 AM on Sunday at Folsom Lake in Granite Bay, CA. Race lengths for the XC course are 6, 12, 18 or 24 miles (1 - 4 laps). Race day registration for the race will cost you $50.
So it still looks like tomorrow's race may actually be dry this year. I haven't seen any trail conditions, but I live near the lake and we really haven't gotten much rain this year, so the trail should be great. It looks like the temperature might be a bit cold in the morning, but the forecast calls for highs in the 60s and light overcast.
For those of you who didn't do the Challenge last year, you can see the race report here. It goes over the course details (another map here) and my poor performance I would imagine that the course will be largely similar - lots of singletrack, some pavement areas and a bit of sand.
You can look in the archives for full coverage of last year's racing.
