Bike broke mountains: high-speed sports are destroying the Lake District’s fells

I applaud the work of Fix the Fells (Lake District in peril due to climate emergency and influx of pandemic walkers, 18 August), but as a regular fellwalker I fear that much of their work is being undone by the influx of Lycra-clad mountain bikers carrying their expensive machines to the top of Helvellyn, Skiddaw etc and pummelling the earth to pieces as they undertake their “thrilling” descents. The Lake District is not a playground. It’s a precious landscape over which we have stewardship. The national park should ban pursuits such as high-speed bike descents and green-lane motoring that undermine the good work of the FtF volunteers.
