Brett Larner has some great info on Shitara in his article on Gold Coast.
Yuta Shitara (Honda), said that Shitara was running GCM mostly as a 40 km training run effort geared toward the Sept. 15 MGC Race. "The main thing is that he comes out of it without any fatigue or damage," he said.
Coach Ogawa told JRN, "This wasn't what I expected, so the most important thing now is recovery and regrouping for the MGC Race. We need to make sure there's no damage or lingering fatigue from this." Evidently that judgment came quickly, as just a few hours after the race Shitara announced on his Twitter feed that he'd be running the 10000 m at the July 22 Hokuren Distance Challenge Abashiri Meet in Hokkaido.
