Foy’s to Blacktail Marathon

Foy's to Blacktail Marathon takes place on July 11, 2027, in Kalispell, Montana, near Glacier National Park. The marathon covers 42 km (26.1 mi) entirely on mountain trails, with 1,524 metres of climbing — roughly 5,000 feet. Start times are not listed in our records.

Five thousand feet of climbing over a marathon puts this well beyond a road 26.2 in difficulty: most finishers will be out for five to seven hours rather than three or four, and the fastest are those who walk the steep sections early by choice. Train with long days on hilly ground rather than with fast road mileage, and carry your own food — at those durations, aid stations alone rarely cover what your stomach will accept.
