The Grand Slam consists of four iconic endurance races, run consecutively over the course of eight months. During the Grand Slam, you’ll traverse deserts, forests, mountains, and high alpine basins, facing shifting weather, technical trails, and true sleep deprivation while covering 200 to 300 miles in each event. All races are point to point or loop courses and fully supported with aid stations and sleep stations.

The Grand Slam includes:

An aerial view of an outdoor event with many people gathered around an inflatable archway labeled 'Destination Trail'. There are tents, flags, and parked vehicles on a grassy and dirt area, with some people walking or standing in lines and others dispersed across the space.

Why the Grand slam?

  • Save $985.00 compared to registering for each individual event

  • One quick, easy registration done well in advance so you can plan your training and next year's races

  • Bypass the individual race lotteries and be placed directly into each of the four events

  • Generous race policies allow you to transfer for two years instead of just one

The fine print

Refund/transfer policies for each individual race DO NOT apply to the Grand Slam registration. Policies for the Grand Slam runners who sign up through these designated spots are specifically designed to help you achieve your goals.

Our Grand Slam transfer policy applies to all four races, not to individual races within that Grand Slam year. If you want to be able to run all four races in separate calendar years, you should sign up through the individual race lotteries.

While we will honor finishers of all four events this is not a competitive event and will not be timed or have top finisher awards.
