FAQs
What are the available route options and their climbing profiles?+
Riders can choose between two distances: the Grande, covering 85 miles (137km) with 6300 feet (1920m) of climbing, or the Medio, which is 45 miles (72km) with 4000 feet (1219m) of climbing. Both routes feature significant ascents, especially for early season.
What is the recommended gear, particularly concerning tires?+
The course features smooth rolling gravel. While some fast riders might opt for 30-32mm tires on an endurance road bike, most participants will prefer a dedicated gravel bike with 36-38mm tires for comfort. Those prioritizing comfort and self-reliance might use 40+mm tires on a touring bike.
What are the registration dates and refund policy for the event?+
Registration opens on January 1st and closes on March 26th. It is limited and fills quickly. Full refunds are available up to 30 days before the event, 50% refunds between 15 and 30 days, and no refunds within two weeks of the event.
What support can riders expect on the course?+
The course will be well thought out and marked, with well-stocked aid stations to help riders refuel. The Grande route will have aid stations at approximately mile 27 and 60, while the Medio route will have one around mile 20. Finishers' times will be posted.
What are the expected weather and course conditions?+
The event is held in late March, when weather and course conditions can be highly unpredictable, similar to spring classics. Average temperatures are around 50 degrees Fahrenheit (10 degrees Celsius), but riders should prepare for anything. Leg/arm warmers and a packable wind jacket are recommended.
Is the Heaven of the South a competitive race?+
No, this is a Gran Fondo, not a race. Participants are required to obey all traffic laws. Times will be posted for bragging rights.
