“Cielos Infernales” was being billed as the world’s toughest track bike race. The first of it’s kind- long, brutal, fast with miles of climbing into the clouds- on one gear in live traffic. 75 miles and 3 mountain ascents completely unsupported. It’s the first time an all-fixed gear alleycat has required the fitness and endurance of a stage race, and the street handling of a messenger. Plus racing in open streets in Mexico City is always a risk. Traffic is wild, roads are rough, and there’s always a chance of a stray pothole, dog, donkey or car catching you out.
