Don't think, run!
First big TTR race. Organized in a completely new course, never used before.
Okumusashi Speed Trail Championship
100% runnable trail course near Tokyo, that has NEVER been open for hikers and runners until now! Get you trail PR in 10K, 21K, or a full marathon, in a well-supported local race. Hot spring and barbecue party at the finish line or head back to Tokyo in time for dinner.
