review of 2016 Mesa Falls Marathon.   

5 / 5 Stars


This is my favorite race I've ever run. I can't imagine there is a more beautiful race in America. I ran St. George just a few weeks after this. St. George is known for its beautiful scenery, but it didn't compare with Mesa Falls. The locals are wonderful. The aid stations are the best I've had in a race with their abundant choices of drinks and foods. The finish line was awesome, again with the best food of any race I've had. The course is half off-road and half on-road. You wind through meadows and forests, right past a gorgeous waterfall, on the highway, *under* the highway, on a beautiful and fun trail, alongside a beautiful river, up a long and challenging three mile hill, through rolling farm land, through two cute small towns that are rural America at its finest, and down a home stretch next to a beautiful park. You even get a free huckleberry shake down the road when you're done. I love everything about this race. Of all the races I've run, this is the one I would most want to come back to, even over Boston. Highest recommendation possible.

Race Tips

Save plenty for the big hill from mile 17 to mile 20. Don't be afraid to take walking breaks at aid stations but especially on the hill. Even with the long hill, this course gave me my first negative split, all because I was sure to leave plenty in the tank for the final 6.2. It was fun passing people along that last portion and finishing strong.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

Book a hotel early. There aren't many in Ashton, but they're all in walking distance to the school where the bus leaves. I was too late and had to stay in Rexburg, 25 miles away.
