mtb…. no idea. never had a computer on bike and most rides are two or so hours up and then blast back down. sure the rides i did as a kid were longer, although flatter and less technical.
road…. 170km in one day using mtb and towing a BOB.
120km on friday. took the fixed bike to town to sort out some tax. saw what a beutiful day it was so carried on riding after having sorted out my tax thing at 8am. didn’t plan to ride but the sun was out, the air was clear, had a beutiful view of the alps so subconsciously (i was stoned) carried on riding south. then saw sign for munich, 60km, pointing in the other direction. so infact it was prob more than 120 as i was staying 15km the other side of the city.
