This is the elevation for the Devil Mountain Double. To the top of Mt. Hamilton is 13,000 feet of elevation gain. There is another 7,000 between Hamilton and the end.

By themselves, these are all hard climbs. Diablo, I think, is actually one of the easier ones. The backside of Hamilton averages out to 8 or 9%. Sierra Rd's average is around 10%. Those sections where it flattens out to 5 or 6% are a welcome relief.



This is the chart for the Mt. Tam Double. RHG plans on doing the first 100 miles I believe. On this ride I think the worst climb is after the Santos Meadow Rest Stop. It's a very steep climb up Rte. 1. It's short and if you had not already climbed Tam, wouldn't be bad. If you didn't have 50 more miles to go (or in my case 150!) I'm sure it could be done on a standard double.
