I would like to suggest that during the race briefing they remind participants that when the y need to walk, they move off to the side to allow others to pass. groups of people were walking together and blocking the route for others.

My first back yard and first ultra in 10 years.
The people make it from the participants and especially the boys and girls in the background beavering away making sure we had everything ready...thank you

The Challenge Running team provides the perfect Backyard Ultra event to support runners. All the volunteers and staff are amazing. A real family feel. Perfect for your first BYU. Thetford Forest is a great venue. The countryside trail are very runnable and beautiful scenery too. One hill but it's the perfect grade and runnable or the perfect walk. The rest of the 'yard' is flat with great surfaces. Mix of grass, hard pack and gravel. I can't recommend Challenge Running enough. Just the best!!
