Stringbean Takes Down D'Haene's JMT Record, a 13-Year-Old on Mammoth Podium + Kristin Johnson's "Unsung" Bear 100 Record (Singletrack News)

Sign Up For The Antelope Island Fall Classic 

This week I'm joined by Alyssa Clark, just back from Mammoth Trailfest. 

We talk about what Tim Tollefson has built there, the 13-year-old who podiumed the Ascent, and where Mammoth fits in the fall 2027 competitive picture. I share my weekend crewing and pacing at the Bear 100, where Kristin Johnson ran 18:50:37 to break the women's course record by over an hour and a half.

It was a big FKT week too: Joe McConaughy's new supported John Muir Trail record, Aurélien Dunand-Pallaz on the GR20, new unsupported marks on the White Mountains 100, and Lindsay Webster on the Presidential Traverse, several tied to Andrew Drummond's $10K bounty purse.

On the business side, we try to make sense of UTMB's 2027 changes to direct qualification and a Trail Waves piece applying game theory to the Run Rabbit Run purse. We close with results from around the world and a 2009 Brett Maune passage on throwing away the other person's timesheet.
