Chamonix has emptied, the barriers are down and the finish arch is in storage — but the trail season is far from over. With Ben Dhiman's sub-19-hour UTMB and Blandine L'Hirondel's historic sub-22 women's run still dominating conversation, attention now turns to a September calendar that offers racing on three continents and some of the most storied hundred-milers in North America.
The UTMB World Series resumes on 12 September with events in Malaysia and Switzerland, giving runners on opposite sides of the world a chance at Running Stones and qualification for next year's finals in Chamonix. The Swiss round in particular tends to draw a strong European field of athletes who skipped, or recovered quickly from, UTMB week itself.
In the United States, the classics stack up quickly. The Grand Traverse Mountain Run sends athletes forty miles from Crested Butte over the Elk Mountains on 5 September, the same weekend the TARC Fall Classic offers everything from 10km to 50 miles in Massachusetts. Ouray's thirteen-mile mountain race follows on 19 September, a short-course test with outsized vertical gain in Colorado's San Juans.
The month's centrepiece is the Bear 100 on 25 September, the point-to-point hundred-miler from Logan, Utah, into Idaho that traditionally closes the western hundred season. Falling aspen leaves, first snow on the high ridgelines and a famously runnable final descent have made the Bear a favourite last dance for runners' seasons — and its finishers list has long served as a preview of the following year's contenders at bigger races. The same weekend, the Red Feather Trail Jamboree brings 50-mile, 50km and half marathon racing to northern Colorado.
For those still processing UTMB week, the lesson of recent years is that September racing rewards restraint. Athletes who raced hard in Chamonix rarely produce their best a fortnight later, and coaches increasingly treat the month as either a first peak for autumn-focused runners or a victory lap for those whose season ended in the Alps. Either way, the trails are quieter, the temperatures kinder and the racing, for a few more weeks, plentiful.
