The 2021 GRT will be held on May 15, 2021 as long as COVID conditions and park approval allows. No spectators will be allowed to participate on race day.
The GRT will offer four events to provide participants a choice of distances to match their experience, early-season fitness, and season-long goals – the 30K Trail Run, the 50K and 50 Mile Ultramarathons and the 50-Mile 5-person relay. Except for a short stretch at the start and near the end, the 30K and 50K events will be entirely on an exceptional single-track trail. In addition to the single-track, the 50 Mile course also includes a section of very runnable, yet very hilly, double-track/fire roads through beautiful hardwood forests.
