In what is a truly international event John Telfer has completed one of the UTMB events, The TDS starting in Courmayeur and finishing in Chamonix and linking the Aoasta valley to the Savoie. At 145km and 9738m of ascent this is a serious undertaking. John completed in 33h 23m 24s 275th overall and 2nd in Class. This is the 3rd completion of the TDS for John and an incredible achievement in this prestigious event.” – Paul Appleby
