Dood your stamina/endurance is stellar for a 40+ guy, I'm 44, just started riding motocross again about 9 months ago and my moto stamina is terrible despite being strong and in good shape
Thanks, were the same age. I do a lot of mountain biking in local trails including sprints and big climbs to stay on top of my fitness. Flowing with the track is a big part of being efficient too. Racing more and maybe some coaching could help
The chuck sun jump, catcher's mitt corner and Leech's Lump were taken out to make more infield space around 20 years ago. The track has changed, but it's still a lot of fun to ride and race.
