4.2.4 The All-Japan Seto Inland Sea Turtle Full Marathon
Rather than competing for time, the greatest achievement is to reach the goal and complete the marathon. The run is held on Shodoshima in the Seto Inland Sea every autumn.
Free bowls of nyu-men noodles are on offer, and there is free use of hot baths for participants. A t-shirt and towel are awarded to all those who complete the race.
