Self preservation has to play in too. Banzaiing and running high risk tech speed
downhills will get you sooner or later.
Common sense (for me).
Where I ride (have ridden) single track in the woods is tight. You're not airing out. Cross Country... you ride up so you can ride down. 25 lb full suspension bikes.
I am not the fastest of the fast, or the slowest of the slow (and getting old too lol), but I ride with self preservation.
If you ride with the expectation you are going to crash, that is a bad mindset, and riding over your head (ya I know, 'challenge yourself').
But I am old school and ride not to destroy myself or my bike. I would not get up from all these high speed/high risk get offs. In fact old enough I stay off technical (ridgeline) stuff these days.
I have been/have moving to a Surron Light Bee ebike (no pedals) and do m/c single track. Ya I know... not a bicycle(!), but based on a downhill bike design mostly (suspension, brakes). Its a phenomenal machine. I still pedal on either a gravel bike or fitness bike (riser bar commuter) for maintaining health. Did Moab & the Flume trail (Tahoe) back in the day... Among other regional rides (PNW).
My back/vertebrae really packs downs so I have to stay away from hammering off road. My riding style/preference is roller coaster/swoopy style trails.
Keep after it gents, and enjoy!
