Rez Loop Challenge

The Rez Loop Challenge is back for year 8! 

This 12 hour event challenges you to complete the 11 mile Ross Barnett Reservoir loop as many times as possible in that time frame. Each loop will start and finish at the RunStrong Training Center. The course will be marked as needed and there will be NO official on-course support. There will be plenty of refreshments, food and shade for participants to recover and rehydrate between loops. Participants are welcome to drop a bag or cooler along the course prior to the event. 

The course is almost entirely asphalt pavement in the form of one of the following: a multi-use path, a neighborhood road that doubles as a bike/pedestrian route, a bike lane along a road, and a short stretch of concrete sidewalk. There is very little shade, and the course varies from hilly to perfectly flat.

Registrants will receive a race t-shirt and some original finisher's swag/custom medal for completing at least one loop. There will be tons of food for runners in between loops. There will be pancakes in the morning, sandwiches throughout the day, pizza in the afternoon, icy cold drinks and water, and a bunch of snacks for runners. 

Don't want to tackle it alone? Take advantage of our relay option where you and up to 2 teammates can take on the challenge by alternating loops. To sign up as a team, have your team captain register and create a team during the registration process. Subsequently, teammates can register and will be able to join the team.

**All participants will be required to have a handheld water bottle or hydration vest/pack at the start of each loop** 

**Summer in Mississippi is extremely hot, and each participant will be responsible for their own well-being. Each participant must carry a phone or be with someone who has a phone at all times. If anybody cannot finish the loop, a number will be provided to call and request transportation back to RunStrong** 

Event clock will start at 6 am and only loops completed by 6 pm will count towards results.

It's going to be hot, humid and tough. Let's see what you've got out on the Rez Loop!
