A bright Sunday morning beckoned members of the Nitos Ciclistas en Movimiento bike club to pedal 64 kilometers out and back from the center of Oaxaca to Teotitlan del Valle in the Tlacolula valley. Fifteen riders took part in the day’s excursion. Leaving from the plaza in front of the grand Santo Domingo church at 8:15 am, the group arrived in Teotitlan two hours later, where they visited the dam and reservoir just north of town before stopping for a late breakfast at the city market.
