This is the first of hopefully more monthly Nam Challenge Routes. For June, time yourself on this route and post your time on FaceBook or Instagram and tag @Nemba.Vietnam. Challenge yourself to do better each time.

The following kudos will be awarded. (We are not sure if we have any prizes so you will have to settle with everyone being very proud of you.)
1. Fastest Time(s)
2. Most Number of Attempts
3. Oldest
4. Youngest
5. Widest Tires
6. Skinniest Tires

1. We don't care how you time yourself, Strava, TrailForks, stopwatch or your little brother counting in his head, but this is for fun and maybe prosperity so be honest.
2. Normal trail rules prevail. Yield to hikers, slow riders, horses, undersized ostriches and any others that are 'going too slow'. If you are caught harassing others so you can beat your time you will immediately be disavowed and/or strongly disliked by the entire MTB community.
