A three-legged race is a running event involving pairs of participants running with the left leg of one runner strapped to the right leg of another runner.^[1] The objective is for the partners to beat the other contestant pairs to the finish line.

The longest distance ever run three-legged in 24 hours is 117.1km (72.7 miles) and was achieved by Gary Shaughnessy (Tadley, England) and Andy Tucker ( Tadley, England ), at Silchester on 9/10th October 2021.^[2] Gary Shaughnessy and Andy Tucker also broke the 12 hour record on the same day.

The world record for the most pairs in a three-legged race is 649, set in 2013 on the Isle of Man. An August 2014 attempt in Canberra organised by National Rugby League team Canberra Raiders failed; only 543 pairs competed.^[3]
