Marathon to Marathon

Marathon to Marathon is run in Marathon, Texas, on October 24, 2026, in the Big Bend country near the gateway to Big Bend National Park. Four distances are on offer: the marathon (26.2 miles), the half marathon (13.1 miles), a 10K and a 5K. The marathon uses a certified net-downhill course billed as the highest race in Texas, and it is a Boston qualifier. Entry includes a technical shirt, transport to the start, a finisher medal and awards, with meals before and after and a party to close the day.

A certified net-downhill marathon at altitude is a specific proposition. The descent can help your finishing time, but it asks a great deal of your quads, so build downhill running into your long runs across a 16-week block rather than saving it for race day. If you are chasing a Boston standard, this is the kind of course worth targeting. The 10K and 5K give everyone else something to run the same morning, and proceeds go to the local health center, school and firefighters.
