The course was a 2-mile loop on an asphalt path. Running on a looping course for 100 miles is fairly difficult mental challenge. This course includes a small hill, making it tougher than I expected. Still, I did managed to come in fourth overall (third men's) with a time that was under 24 hours.
The course is only 1.061 miles long. The goal is to complete as many laps as possible within 24 hours. The views of the Golden Gate Bridge and San Francisco's New Years Eve fireworks display are pretty amazing. These images were taken during my best finish: 108.2 miles.
