#3. Winter mountain biking
Winter’s here and the trails have turned from grippy hardpack to slippery mud. Roots and rocks slime up
and dips ﬁll with water, sludge and hidden rock. The Merida Brass Monkey mountain bike series, co-run by the army, consists of two or four-hour races with flowing single tracks and technical sections to keep you concentrating. They go ahead whatever the weather but the organisers thoughtfully provide a bike-washing station at the finish.
