Yes, it's an old janky structure, but it's one of 3 structures in this riding area and it's so beloved that people have removed large blockading piles of cedar from the entrance three times so they can ride it. (At least until someone went through a couple of the rungs towards the bottom)

The ramp is on an intermediate trail and drops about 6' over its 21' length. The dimensional lumber was slick as snot if the air is a little humid (never mind actual rain) so skidding down the ramp was a factor.

Less experienced riders would start down the ramp, grab a little brake to control speed (no effect), grab a little more brake to control speed (no effect), DYNAMITE THE BRAKES BECAUSE THAT BERM AT THE BOTTOM IS COMING AT ME WAY TOO FAST AND I'M TOO YOUNG TO DIE! (no effect) ...then slide off the bottom of the ramp and skid through the dirt towards the berm. The masonry blocks below the ramp were an attempt to control skid erosion. The new ramp will be extended to cover that area.

I expect that split cedar will be much grippier and will allow a little speed control even when wet, but there will probably still be a some skidding. As a result, the rungs are going to be 3.5" thick to allow the possibility of one re-surfacing if a groove gets worn into them.

The current slabs available for rungs range from 8-16" wide (30x16x3.5", for example) You can just make out some of them piled on the take-off ramp in the recent picture. The question is: should they be split further?

Here's how I see things:

• More narrow rungs give more biting edges for braking, but they also give more opportunity for wear
• Wider rungs are stronger/more durable
• Wider rungs are more likely to have grain twist and not sit flat against the stringers leading to rung rocking and nail pull-out
• Narrower rungs require less total rungs to cover the area because you have more spaces
• More spaces give better cleaning/drainage, but that's more of a factor on the flat take-off ramp, not the downhill portion

Anything critical I've left out?

I think the way to go may be to keep the big slabs relatively large, but alternate, so there'll be a 10" rung, then a 6", 10"...

Cinco de Mayo - Physiotherapy Trail Day

Yesterday felt like we could have actually been in Mexico as BC was breaking records for the hottest May 5th. We might have broken our own record as 35 people came out to volunteer more than 150 hours of labour to the trails. That should definitely earn everyone some serious trail karma!

Physio was in pretty rough shape as it continued to see riders throughout the winter. Some of the soft spots were starting to get deep and root exposure was becoming troublesome in a few areas. We filled in the holes that were forming on either side of the new bridge on the lower section and pretty much laid new dirt on a 1/3 of the trail. Some sections were dug out and stabilized with rock and mineral soil and new dirt was added to some of the eroding steeps. In short, we accomplished a lot of work in half a day. We wouldn’t say that the climb has been dumbed down but one of the trail builders summed it up well with “now there are no excuses …”

A lot of new and old faces came out and brought their skills, strong backs and love for the trails with them! Thank you to everyone for coming out instead of drinking beer (or mojitos) on the patio :)

Some people walked away with some pretty awesome swag so we’d love to give a special shout out to our awesome sponsor for the day: Cap's Westwood Cycle

it'll be a low key event doing groundwork to fix up some lines, maybe replace a slab down ramp with a ladder instead and possibly cut in a ride around for a section. i'll be driving up from old buck @ 2:30pm (so should be on the trail by 3:00) and will stay until about 7 depending on how things go and if anybody is there to throw rocks at me.

Hey Trail Builders,

MEC will be hosting a trail day on Expresso this Thursday, April 25th.

We will be meeting at 8:30 am just past the yellow gate on Fromme. Caome for some or all of the day.

Please email ash@nsmba.ca if you are up joining, and she will be sure to bring you some yummy food for lunch!

Cheers, :fix:
