We do quite a lot in our local area:
We helped develop the trail map.
We do a lot of trail maintenance (clearing deadfall, repairing rain/rider erosion damage, building new sections, etc.)
We also help out with local events (free guiding, uplift, use of our van/trailer/hire bikes/etc).
We've run a few free uplift days for local riders too, late and early season. But when we say local riders, we do mostly mean our mates! 😉
Should probably do even more really, as we are a mountain bike business and couldn't exist without the local trails and facilities. We have a couple of bigger local trailbuilding projects planned for this autumn, hopefully we'll have time to get them done!
