Shitara is probably most well-known outside Japan for going through halfway under 62 minutes during his marathon debut at this year's Tokyo Marathon and still ending up with a 2:09:27, but he's been turning heads in Japan since his second year at Toyo University when he broke a stage record at the 2012 Hakone Ekiden and outkicked the U.S.A.'s Dathan Ritzenhein to finish in 1:01:48 at the NYC Half two months later, until this year the fastest time ever by a Japanese man on U.S soil.
Three weeks before Tokyo this year he ran a 1:01:19 PB at the Marugame Half. Many people would call that a solid tuneup three weeks out from a serious marathon, but eight days? In Prague both Shitara and his coach Satoshi Ogawa told JRN that he planned to run "marathon pace," 3:00/km, ahead of a planned shot at 2:07 in Berlin. Finding himself right behind eventual women's winner Joyciline Jepkosgei (Kenya), Shitara ratcheted up the pace and ended up as the top Japanese finisher in 28:55.
A week later and he was way faster, going through 10 km just off the Japanese NR in 28:10 and rocking steady to beat all the other next-generation Hakone stars transitioning to life in the longer distances, Suguru Osako (NOP), Kenta Murayama (Asahi Kasei), his twin brother Keita Shitara (Saitama T&F Assoc.) and others, to Sato's antique 1:00:25 mark.
Surely that's faster than his planned pace in Berlin. It has to be a confidence builder, but it''s almost equally surely too much a week and a day out from a hard marathon. After Tokyo Shitara said he would definitely go with the leaders next time. Ogawa told JRN in Prague that compared to Tokyo Shitara's stamina is far improved now.
