Starlight Theatre Mas O Menos 100K Mountain Bike Endurance Fest – Terlingua, TX
The MasOMenos 100k is a Marathon Event. Prizes and trophies are awarded (generously!) for marathon events ONLY: the 30K, the 50K and the 100K. TMBRA Spring Series and USAC Ultra-Endurance points are culled from those results by TMBRA officials at the event and points are awarded that may be used in those two series. There are no prizes or honorariums for those points designations: ONLY for Marathon results.
Pre-registration is now OPEN! You can download a form from this site, or pre-register online at bikereg.com.
