Grand Teton & Yellowstone

Grand Teton & Yellowstone starts from Jackson, Wyoming, on June 4, 2027. Two half marathons (13.1 mi) and two 5K races (3.1 mi) are offered, one pair themed on Grand Teton and the other on Yellowstone, through the landscapes of the national parks. Start times are not listed in our records.

Running two half marathons across consecutive weekends in the same region is a popular way to combine a holiday with a training block, but it asks a specific kind of fitness: the second is run on legs that have not fully recovered. Treat the first as a controlled effort at ten seconds a mile slower than race pace, and you will run the second faster than if you had raced them both.
