Take the Real Ale Wobble
United Kingdom's Top 20 Adventures
If mountain biking has always seemed a little on the serious side for you—too much panting uphill and getting muddy—you might want to give this a try: cycling through the Welsh hills drinking Felinfoel's Double Dragon and Tomas Watkin's bitter. The 25-mile off-road route is clearly marked, so that even with double vision you would have a hard time getting lost. There's a guide to make sure you get home, so you can drink as much as you like. The exercise you get in between the drinking stops is generally enough to work off the booze from one pit stop to the next. Look out for red kites (Britain's rarest bird) as you wobble over the hills. Gluttons for punishment should ask about the 20-mile bog-leaping point-to-point race.
