Anyone already crossed the Alps? This summer I would like to cross the St.Gotthard, and down to Locarno. - that is about 1700m ascension and about 125km up to the pass, then 90km and 1800m down to the Sc at Lugano. Should I supercharge my X100 at Beckenried or will it make it the 125km to the top with 100% charge? Any opinion?
