Boulder 100 & 50K
Overview
Boulder 100 & 50KEndurance Running Race
Boulder, Colorado
October 12-13, 2013
Fast, flat course with lots of aid stations. These races are run on the trails around the beautiful Boulder Reservoir. They consist of 7.14 mile laps and runners will be given 30 hours to complete the 100 mile course and 8 hours for the 50K. Any 100 mile runner dropping before the 24 hour mark will automatically be given an official distance in the 24 hour solo category. It is a fast course with approximately 1,400 feet of gain and loss for the 100 mile and 420 feet for the 50K, with a mix of pavement, dirt roads and non-technical singletrack. With aid stations every 3.5 miles runners will enjoy Hammer Gel products and sports drink out on the course and a great mix of foods and drink at the Base Camp aid station, including pasta and hot soup for the 100 milers at night. They will be run simultaneously with the 24 Hours of Boulder so there will be a lot of aid, great support and lots of energy.

Recording Laps
Racers must log-in on each lap at the Base Camp located at the Start/Finish area. There will be a running clock, therefore the lap splits will run from lap-end time to lap-end time. It is the racer’s responsibility to verify that you are logged-in correctly.

It is important that you check in at the aid station or your lap will not count.
