The hares mark their trail with paper, chalk, sawdust, strings, or colored flour, depending on the environment and weather.
Special marks may be used to indicate a false trail, a backtrack, a shortcut, or a turn. The most commonly used mark is a "check", indicating that hashers will have to search in any direction to find the continuation of the trail. Trails may contain a "beer check", where the pack stops to consume beer, water, or snacks, allowing any stragglers to catch up to the group.

An event held annually by some chapters is the "Red Dress Run". In 1987, Donna Rhinehart was taken to a hash in Long Beach, California, to be introduced to the sport. She was invited to "wait in the truck" until her host returned. Instead Rhinehart joined the hash in her red dress. The following year, the San Diego Hash House Harriers sent Rhinehart an airline ticket to attend the inaugural "Red Dress Run". Hundreds of hashers wore red dresses for the event which was widely covered by local media.
In addressing the crowd, Rhinehart suggested that such hashes might be held to raise funds for local charities. Today the Red Dress Run is another part of the Nash Hash in Nigeria (an annual event hosted by different kennels in Nigeria).

The Bob Marley Run is PHH3's special event, celebrating reggae legend Bob Marley with a themed hash run and lively festivities.
