I did this summer’s local socially distant XC time trial series on my cross bike. I typically would catch my minute man on the uphills but then they’d recatch me on the descents and then just ride away and I’d never see them again. I’d spend the entire race laser focused on the jagged outcroppings and my hands and arms would be sore and tired after 20 minutes. I usually finished mid-table in my division. It was great, but next year I’m getting a proper MTB.
