Is there a time limit? / Do you allow walkers?

Yes, the half marathon has a time limit of 4 hours (approximately a 18 minute per mile pace). If you’re not on pace to finish within the time limit at the halfway point, you may need to be picked up by our shuttles, or turn around. The 5K has a time limit of 1 hour (approximately a 19 minute per mile pace) due to the half marathon coming up from behind and, if not on pace, you may be asked to finish as a pedestrian. You will receive a finisher’s medal regardless of your finish time.

For your convenience, use our downloadable pace table to help estimate your finish time when you register. In order to group together similarly-paced runners, base your estimate on your most recent training run or race results.
