Hello to everybody!
My question regarding the trail of UTMR: which is/are in your opinion the most tiring and technical part of the UTMR. I will run the Ultra 116km.
As tiring , if I see the altimetry, I could hypothesize the climb from Alagna to Colle del Turlo and from Macugnaga from Passo di Monte Moro.
Thank you in advance.
