I did trials competitions for about eight years. It's a huge amount of fun but also very humbling for people like me who don't have unusual amounts of talent. Its kind of like long range pistol shooting- every once in a while you get something right and you're like wait, what?
One of my childhood heros was Dick Mann. He's a NorCal local and in addition to dirt track and road racing has always been into trials. He makes super nice vintage British trials bikes. They're museum quality but he will only sell to people who are going to ride them. And he rides (or rode when I was doing trials), we'd see him out at our practice areas. Anyhow he was the grand marsal at an AMRHA weekend at Sears Point and I was there to ride the trials on my Montesa Cota 348. He decided to help out by checking the trial on my second loop and happened to be checking this one section that some people found difficult but for whatever reason I had wired. I did another clean and he complemented me on my ride as he punched my card. Made my entire trials "career".
At another AHRMA trial there was a really gnarly descent on the loop. I'd seen a guy crash there the previous lap so was going slow, and Montesa brakes are not that great. Dick was riding that day (and was like 75 then) on some heavy British bike. He passed me on that descent, on a heavier bike, going much faster. On the way by he gave me a look like "why are you so slow?". That was more the normal order of things.
One of the many good things about trials is that the bikes are quiet and you can practice in a small area. I started when we lived in town and could move both cars off the driveway and use that for a practice area. Part of the reason we moved to the mountains was to have a place to ride. The bikes never bothered the neighbors, they're quieter than chainsaws and leaf blowers.
