Ben Nephew set a high bar for endurance, pain tolerance, and speed during his victorious 2015 performance at the Mt. Tammany 10, and it took an even better performance to dethrone Nephew in 2016.

That’s exactly what Jason Lantz did, though. Lantz, 34, of Lancaster, Penn., posted a winning time of 7:05:18 during the fifth running of the Mt. Tammany 10 on Saturday, March 19, in Delaware Water Gap, N.J., eclipsing Nephew’s previous course record of 7:33:00 set last year.

Mt. Tammany 10 is a 40-mile race consisting of 10 loops of the course, 10 ascents and descents of Mt. Tammany, and approximately 12,000 feet of vertical gain – all within a 10-hour time limit.

Nephew, 40, of Mansfield, Mass., crossed the finish line in second place, side-by-side with Jay Lemos, 26, of Clifton, N.J. Their time of 7:45:11 is the third-fastest ever on the course, giving Nephew two of the three fastest times ever run at the event.

A total of 14 runners completed the race within the 10-hour official time limit, and 20 runners ultimately completed all 10 loops – the last two crossing the finish line in just over 12 hours.
