Day 2 also starts at the crack of dawn and racers have until 5pm to finish. The 79 km feature a fearsome climb of about 6,000 feet, from Tres Ríos straight up the Irazú Volcano, with the high probability of bitterly cold weather much of the day. Starting at 1291 meters above sea level, the ride is a never-ending ascent until competitors reach 3025m (about 10,000 feet). Then it levels off, passes the Turrialba Volcano, and starts one of the fastest and longest downhills in Costa Rica, finishing in the town of Turrialba at an elevation of 607m (about 2,000) feet. On this day, it is very important to have well-functioning brakes and be prepared for cold weather riding. At 10,000 feet with wind and rain, hypothermia is a risk, as it can get near freezing.
