With the National Mountain Bike Championship coming up in a couple of weeks,

a joint project by SACA-Dirtraction-National Parks Board is in hand again to rework the various sections of Bukit Timah Mountain Bike Trail.

The section in question this time is the exit of the trailhead to the visitor centre, where for years (at least a decade!) this fall line climb been eroding, patch up with quick fixes,

rebuild with water bars and tarmac blocks, and the cycle goes on years again.

With 1 month of pre-planning, we managed to gather the resources needed, rocks, earth, surfacing material and manpower for today build.

A series of 5 switchback will be added to this short section, cutting the fall-line into 7 segments.

The trail resemble previous work done a few months ago at Tampines Bike Park, with rollers and dip incorporated into tight corners to keep the ride interesting.

What made today different from other trail project done, we spent a good amount of time reforesting the old trails, replanting and relocating at least 15 young trees so to keep the old trail out of sight, and presentable the moment we finish it.

It’s been some months since we’ve touch the trails.

Bukit Timah Mountain Bike Trail, centred around an important conservation area is heavily used every weekend, and with the combination of heavy traffic, user conflict adding to a pretty much ‘old-school’ mountain biking trail design,  the trail is in need of some work in order for it to sustain our tropical weather and conditions.

With the upcoming Singapore National Mountain Bike Championship,  we took the chance to fix one of the critical yet easy fix for this 13yrs old trail network.

The trailhead is an important gateway to a mountain biking network. It provides visual clues on what’s expected and prepare riders to meet the trail challenges ahead, pretty much a natural signpost in some way.

With the importance of a symbolic trailhead in mind, we figured a rock armored climb would be ideal to fix this once and for all, a good and highly sustainable solution for this 23% graded slope.

The previous season(s) effort by general civil engineering contractor trying to do a quick fix, with the all almighty cement, was horrible. The trail head looks dreadful weeks ago, with sharp broken cement blocks creating cutting surface for some unfortunate shin and knees, in which the earth had hollowed out below the cement surface, there no other way to fix this unless we take away what’s left of the cement and redo the trail with proper mountain bikes rock armors.

National Parks Board coordinated the effort with SACA and Dirtraction. Our plans is to to get the trail head fix before this major event.

Supply chain for rocks choke up in the past weeks and we finally got the call from Nparks late last week, that we are to do the fix early in the week, in which normally we wouldn’t want to touch the trail so close to the event.  We guess is better now or never and we started the process on Tues 13th Oct 2009.

The excavator came in and removed the concrete within 30minutes, paving our way to work on the rocks all day.

With some help from general workers, we got the rocks man-hauled up the slope one by one, barrow by barrow, roll by roll.

The process is lengthy and Jason, Jeff and me toil through the afternoon with the meticulous rock puzzle which will make or break the climb.

A total of  34 man hour is spent today, in which we managed to all the rocks pitched, minus the last 2metres of the exit in which we are forced to stop as nightfall.

The last 2 metres is completed the next day, together with some test riding (that’s always the interesting part) and further modification so to make it flows better.

Stuffing earth between the cracks will be on going for the next few day and we hope this will give Bukit Timah Mountain Bike trail a new image of sustainability and fun.
