Hermes Half a Half Marathon

Hermes Half a Half Marathon is held in Lakewood, Ohio, on March 20, 2027. As the name suggests, the single format covers half the half-marathon distance: 10.5 kilometers, or about 6.6 miles, starting at 8:00 a.m. That puts it between a 10K and a 15K, an unusual length that makes for an honest hard effort without the recovery cost of a longer race.

This distance suits runners who have a few 5Ks behind them and are curious about going further, and it also works as a sharpening race in the middle of a half or full marathon build. Pace it a touch more conservatively than a 10K, since the last mile and a half is where the distance shows. To prepare, hold a long run of about eight miles in your week and add a weekly tempo of twenty to thirty minutes at comfortably hard effort in the month beforehand.
