A practice or skill course is perfect for introducing beginners and advanced riders to the sport of biking and for further training in it. The practice terrain, which normally has hardly any slope, allows you to approach new obstacles and techniques without great danger. For this purpose, situations such as hairpin bends, heels and root passages, which mountain bikers can also encounter in "the wild", are simulated. This allows targeted training for "outdoor use" to improve coordination and balance. Typical obstacles are e.g. wooden bridges, balance elements, heels, waves, steep curves and other obstacles made of earth or set stones. The setup of the exercise course can range from mobile elements in a flat area to specially prepared trails of varying difficulty.
