Did you pack your climbin' legs?
Moving the start to Targhee means that the Bustle Creek climb comes late in the lap. Ouch.
We attempted a pre-ride of the entire course yesterday but heavy rain on Saturday left the Rick's Basin singletrack too wet to ride so we skipped the first 5-6 miles of the loop. I am still not sure how long a lap will take me at endurance race pace but I think it will be more than 2.5 hours. There is about 3,900' of climbing per 25-mile lap.
