no knee-shaking rides yet, but I bet that’ll change once I get out onto Bell Isle, Buttermilk, or Northbank. there have been some sections of deep run park that I tried and I was going a bit too fast for my skill level and almost had my feet part ways with the pedals which was a bit worrysome, but other than that nothing. when I get on Buttermilk, there is one section that from what I’ve heard has sick exposure so I’ll take that section slow until I build up my skills a LOT more. one mtb’r didn’t do this and died in that section because of it. may he rest in peace
