Grand Teton Half Marathon

An early-summer half marathon in Jackson Hole, and the biggest and best-organized of the valley’s three local halves, with around two thousand runners. The course runs from the Stilson Lot out toward Wilson and back, crossing the Snake River before turning up Spring Gulch Road, with the Teton Range in view all the way to the finish at the Jackson Hole Golf Club. Mostly flat and fast, run at altitude (about 1,905 m), with great swag and gorgeous scenery.

    Last year I surprised myself on the run at Ironman 70.3 Coeur d’Alene—I came out of T2 like a bat out of hell and it ended up being my fastest run split in a 70.3 to date. There were probably multiple reasons for that, including the shortened swim, but I think one factor was the Grand Teton Half Marathon, which I had raced two weeks prior. That was also my fastest half marathon to date, and I suspect that strong run kicked my running fitness up a notch or two just in time for the race.

    This season, I’m putting that hypothesis to the test by racing not one, but two half marathons before this year’s edition of Ironman 70.3 Coeur d’Alene. The first one was the Jackson Hole Half Marathon two weeks ago, so without further ado, here’s a quick race report about the Grand Teton Half Marathon, my last running race before heading back to Idaho later this month.
