Pushing through bramble, scurrying down a cement underpass, leaping over a small creek, dashing through the yards of unwitting Washingtonians, the runners race after the "hare" and strain to hear the cries of "On-on!" This seemingly chaotic adventure is actually the organized sport of hashing, an event that's part human fox-hunt, part treasure-hunt.

In hashing, a leader, or the hare, sets a three- to five-mile trail by dropping clumps of flour to mark the way. The rest of the runners, or hounds, race after -- remaining wary of possible false leads. Front-runners let followers know they are on the right trail by yelling "On-on!" to those in the rear. In the end, the red-faced, muddy-legged, sweaty crowd quenches its thirst with the treasure: ice-cold beer.

Hashing, started in the 1930s by British civil servants stationed in Kuala Lumpur, begins and ends with a circle. Here, hashers celebrate birthdays, tease first-timers, "punish" each other for misdeeds such as wearing new shoes and bequeath regulars with bawdy nicknames. The rest of the crowd chants "Drink it down, down, down, down . . . " as the hasher guzzles beer, then tosses any leftovers overhead. The quirky subculture, whose members bill themselves as "a drinking club with a running problem," finish with a trip to a local pub.

What to Expect: An easygoing camaraderie that's part prank-fest, part frat party -- except there's no pressure to drink (soda and water are available). Hashers are incredibly welcoming, but expect plenty of teasing. If you're easily offended by salaciousness, this crowd's not for you. For those who like the idea of the social scene but haven't huffed and puffed along a running trail lately, don't worry: Walkers are welcome.

What to Bring: Running shoes and workout clothes. You may want to wear knee socks or pants to protect against running through thorns. Do not wear any legitimate race T-shirts, or you'll have to drink it down, down, down, down . . . .

Cost: $3 to $5 to offset the cost of beer and post-run snacks.
