The event takes place across Saturday and Sunday as part of a festival format that includes daytime and evening running options.
A Dark Divide Night Run is included in the festival as a Saturday evening event that shares trail with the 100 mile and 100k fields and provides an opportunity to run on trail after dark.
Logistics note: beginning in 2025, runners and crew for the 50K and 25K events (excluding the Dark Divide) are required to park at John Wesley Ranch, with shuttle vans transporting people to and from the start and finish. The shuttle ride is approximately six minutes. Visit the organization's website for the most recent information.
