A guy I know was on his first solo mountain bike ride when he started cramping up. Had that first bike / new hobby stoke and was trying out the route we’d shown him the week prior. He hadn’t done a ton of long cardio activities in a while, and ended up getting roasted on a hot day. Mega cramps had him walking the final trail back, with some sit downs and some groaning. Those really gnarly leg cramps that just debilitate you. Not particularly funny. Until a rider came by and helped by offering water and an energy packet...
