★第60回「お好みマラソン（150分間）」※東温市ダム湖畔コース 2026

On the dam lakeside course, this 60th running has the loose, choose-your-own-adventure feel of a race designed by runners who got tired of being bossed around by split charts. The motto is basically “Okonomi is best!”: run as you like, as much as you like, and keep it cheerful rather than heroic. The format is a “freewheeling okonomi run,” with up to 150 minutes to use however your legs and mood decide. Expect a steady lakeside rhythm more than a point-to-point mission, with the finish line feeling like wherever your personal plan finally says enough. The quirk is the freedom: “as much as you like, your way,” plus a participant-only option called the “Easier Than Now! Class” if you want a little running wisdom with your pancakes-and-miles energy.
