FAQ
The half marathon and marathon start in Jordán, at the bottom of the canyon, about 2 h 30 min – 3 h from San Gil. The organization takes runners on buses that leave in the early hours from El Puente Shopping Center; there are also departures on Saturday at 11:00 a.m. and 3:00 p.m., included in your entry and booked in your account ("Transport to Jordán"). Check the times in the schedule and on your distance page.
Yes, at the authorized crew-access checkpoints (PCAA), where one supporter per runner may give you food, drinks, clothing or a massage:
They may accompany you from 100 m before to 100 m after the checkpoint. Anywhere else it counts as unauthorized assistance and is penalized.
The cut-off is the latest time you may leave a checkpoint. If you don't check out in time, you are out of the race, and once a checkpoint closes the organization's services there end. If you decide to withdraw, do it at a checkpoint and hand your bib to the judge, or report it immediately to the race incident line printed on your bib. Transport from where you withdraw is at your own expense.
Distance and elevation may vary between watches, apps and mapping software. To plan your race, go by the kilometer marks in the official checkpoint table for your distance.
