This is an unsupported, unmarked, free, fat ass style 50k trail fun run at the White Mesa bike trails near San Ysidro. It is about a 45 minute drive from ABQ.
White Mesa contains some of the most unusual and spectacular scenery in New Mexico. The course is absolutely crazy.
4 loops + 1 short out and back. Every trail intersection has a detailed map and location marker so it is very easy to navigate. Loops 1 and 3 are clockwise, loops 2 and 4 are counter clockwise. The map below shows the sequence of markers. Just follow the trail and you will be ok. Each loop, you will record you time on a clip board. You will have access to your car at the end of each loop. You can also do a shorter combination of loops for a marathon, half marathon, or other distance.
