Endurance Buzz Adventures LLC will once again hold trail races at Possum Kingdom Lake.
Races of 20 and 55 km and 52 miles begin at 8 a.m. tomorrow, Saturday, headquartered at Bug Beach on the peninsula, utilizing the hike and bike trail system.
The course distances have been measured with a Rolatape Professional Series measuring wheel.
There is a four hour, 15 minute, time limit  based on the 52 mile and 55 km start time.
No race week or race day registration will be allowed.
There will also be a free 12-and-under kids fun run .4 mile loop around the Bug Beach area beginning at 8:05 a.m.
Youth will run one or two loops depending on their age and parents must sign a waiver and pick up a luck-bib number at packet pickup.
All finishers will receive a finisher’s gift. The gift will be a local item and will not be a traditional medal.
There will be packet pickups the morning of the trail races, on-site professional medical support, aid stations with fluids and an assortment of sugary/salty items that are cup free.
Runners are asked to bring their own water bottle or hydration system.
BRA officials noted trails will also be open for public use.
