I recently ran the UTMF, one of the must-do races for me. However, things didn’t go too well and I DNF-ed at ~100km, due to the inflammation of my ITB.
That being said, I hope this post will be useful for future runners, as I was caught unexpected in parts of the race.
This year the race was set in a clockwise direction with 169km and 9500~m of vertical. Comparing the 100km I did to the Lavaredo Ultra Trail, the verticals were less steep, but still one to reckon with. OF course I missed the Tenshin mountains at UTMF, which is said to be the toughest 20~km.
