He then rigged up his own little kill switch he grabbed off a moto and wired it up so he could hit the start/stop button with the flick of his thumb on the handle bars.
The moto kill switch timer is a pretty common thing people rig up though for a timer device.

Granted I ride a lot of technical XC on my big bike, and only do lift serviced DH a couple times a year, and blue mountain is not whistler.
My brother though had his speedometer rattle apart just riding to work. I guess you have to shop around.
Another higher-budget alternative is to put a GPS in "record tracklog" function and stuff it with some padding in your camelback. In addition to recording all speed functions, it will map and give vertical profiles of all your trails.
Of course, to see your speed in real time you'll need to mount the GPS on the handlebars, which is NOT a good idea for the reasons everyone else is giving.

hey, get a watch with a stopwatch function, start it, wait till 10 seconds after you press it (you press it at 00:00:00 and start at 00:00:10) and when you finish wait about 10 seconds after you finish the run and stop it (finish at 00:07:32 stop it at 00:07:42) and just take 20 seconds of the final thingy, it's not super accurate but it gives you an approx. time

On the wide-open stretch at Blue mountain some of the DM guys figured they were going 50-60km/h, but I knew that I was clocking in the mid-70s, and those guys were going a LOT faster than me.
I find it odd that people wouldn't want to quantify their rides, at least as an option.
