The mighty Titan Zapoteca marathon race held each spring in San Pablo Guila has become one of the premier mountain bike events in Oaxaca state. This year’s installment, which took place on Sunday, 26 March 2017, attracted over 400 registered participants — and a number of non-racing followers, like our little gringo group. As in past years, the race course was very challenging, with multiple long climbs and many treacherous descents. The race course is formidable, running for 42 km (26 miles) through the countryside, with steep climbs and scary, very technical descents. The total elevation gain and loss on the loop course amounts to over 1128 meters (3700 feet).
