The Trans Sierra Norte is a multi-day enduro mountain bike race that rips through the Oaxacan highlands offering more than 3,000 feet of elevation gain/loss. The trails are thousands of years old and were predominately used to connect local villages and exchange goods, further making the bike event a cultural rarity. Especially since it finishes in Oaxaca City right about the time the fireworks are blasting off for the Day of the Dead fiesta (Dia de los Muertos).
