A new "gravel" event the day before the Santa Fe Century. Test yourself on the Gravelón 55 mile course or dip your toe into gravel with the Gravelito 25 mile tour.. The Gravelón has registration options to race it or ride it like a tour. Racers that also do the Grand Fondo century race on Sunday are eligible for overall prizes. Visit the Santa Fe Century website for the race lowdown and registration.
