I’m in my 40s and my training runs, they still are 😜 much faster! If I take 10 minutes per mile I’d truly feel like a turtle. Not uncommon in the District itself to take an hour to go a few miles by car. Many bike, metro or walk. I have yet to truly feel brake fade even in hot traffic but the stopping curve is ‘very linear’. Hopping into to the 68 Mustang from late model cars has truly re-taught me the art of patience, distance and not driving like a douche all over again 😁 I truly realize that no one is getting anywhere any faster and this makes me a better and kinder driver even in my modern performance machine.
