What are the current organized efforts to break the two-hour barrier? (That said, one of the exceptions is the women’s marathon world record of 2:15:25, set by Paula Radcliffe in 2003, which remains qualitatively superior to other women’s distance records.) It’s rare for a world record in one event to be much better qualitatively than other contemporary world records. Translation: A sub-two marathon would be a performance far superior to that ever produced in any other endurance event.

Those latter marks are roughly in line with the current marathon record. The current world records for those distances are 12:37, 26:17, and 58:23, respectively. According to the Purdy tables, the most respected race-comparison tool, a 1:59:59 marathon is the equivalent of a 12:20 5K, 25:49 10K, and 57:12 half marathon.

While running six seconds per mile faster in a race is often achievable for regular runners, it’s a huge accomplishment for world-class runners.Īnother way of considering a sub-two marathon is to compare it to equivalent times at other common distances. The current world record was run at an average pace of 4:41 per mile. Put another way, that’s almost eight and a half consecutive 5Ks in 14:13 each. Running 1:59:59 for the marathon entails averaging 4:35 per mile for 26.2 miles. Dennis Kimetto after setting the marathon world record in Berlin.
