Honest conversations with trail running industry pros, and fans who love the mountains. One of the longest running podcast in the scene. This is Singletrack.  

This news made it through the inter-grapevines yesterday and sadly got confirmed this morning via an official post from Jeff’s family on his IG account:

During the TDS race at UTMB in Chamonix, Jeff suffered a heart attack. He received immediate medical treatment from the race and emergency medical teams before being airlifted to the hospital, where he remains under medical care.

Sending all the prayers and well-wishes to Jeff and his family at this moment.
