Yuma Hattori was planning to make his marathon debut inthe Tokyo Marathon 2015, but because of the last minute injury, his marathon debut was postponed for a year until 2016. In his debut marathon, Hattori was 12th with 2:11:46.
Hattori's possible talent for the marathon was made apparent at the 2014 Kumanichi 30Km road race in February of 2014. Hattori broke the Japanese Collegiate best for the 30km road race with 1:28:52. It is also the third fastest 30km time by Japanese, tying the 30km personal best of legendary marathon runner Toshihiko Seko.
Hattori will be running his second marathon in Tokyo.
People use to say that second marathon is actually harder than the first, but that may not be the case for the younger generation of runners. Hattori recorded two consecutive stage-best in the second stage (where the team's big guns run) of the 2015 and 2016 Hakone Ekiden. In January of 2017, Hattori ran 22km stage (where the team's big guns run) and was only 12 seconds behind the stage winner in his first New Year Ekiden, All-Japan Industrial Men's Ekiden team championships. Hattori seemed to be in shape. Can he improve his marathon best ? Can he crack 2:10 for the marathon?
2015年の東京で初マラソンに挑むはずだった服部勇馬だ が、故障で直前にキャンセルとなり、デビューは１年遅れ た。2016 年の東京マラソンで念願の初マラソンに挑戦し、2 時間11分 46 秒で12 位だった。
服部のマラソンへの適正の片鱗は2014年２月の熊日30キ ロ・ロードレースで1時間28 分 52 秒の大幅な日本学生最高 記録を樹立した時に示された。このタイムは日本歴代 3 位 タイで、伝説の瀬古利彦（現・DeNA 総監督）が1987年に打 ち立てたタイムに並んだのだ。
今回の東京で 2 度目のマラソンに挑む服部。以前は初 マラソンよりも2 度目のマラソンの方が難しいと言われた が、最近は2 度目で自己ベストを更新する若手選手が多い。
2015 年から箱根駅伝の花の2区で 2 年連続区間賞を獲得。
初めての全日本実業団対抗駅伝では最長区間の4区で区間 賞から12 秒遅れの5位と、今年も好調だ。2度目のマラソン で自己ベストを更新できるか？ そして2時間9 分台に突 入できるだろうか？

Perhaps because Hiroyuki Yamamoto, who made his marathon debut in the 2014 Hokkaido Marathon in Sapporo, collided with the aid station table, he finished dismal 17th with slow 2:21:54. It was far from noteworthy marathon debut. However, 2:11:48 Yamamoto recorded at his second marathon, 2015 Beppu-Oita Marathon, was respectable time.
His half marathon best, 1:02:43, is relatively modest but that may be because Yamamoto has not run any half marathon in the last three years. His 5000m best is 13:45.43 from 2010, but in the 2015 Golden Games in Nobeoka, Yamamoto ran 13:45.75, close to his personal best. In the 2015 Hachioji Long Distance meet in November, Yamamoto improved his 10000m best from 28:24.93 to 27:55.40. In the last three New Year Ekiden, All-Japan Industrial Men's Ekiden team championships, Yamamoto always finished in top three in approximately 15km stage.
In November of 2016, he came within one second of his marathon personal best at the 2016 New York City Marathon. His fourth place finish in New York City Marathon, the best Japanese finish in the history of New York City Marathon, is quite respectable. Note that since the New York City Marathon course is hilly and thus much tougher course than Beppu-Oita Marathon course, where he recorded his personal best, Yamamoto's performance in New York is much better. Furthermore, the level of elite field in the New York City Marathon is much better than any of the Japanese marathons save Tokyo Marathon. Since this year's Tokyo Marathon course is expected to be much faster, Yamamoto, who ran 2:11 in much tougher New York course, may be ready to crack 2:10 in Tokyo.
2014 年北海道マラソンで初マラソンに挑んだ山本は、給 水テーブルにぶつかって転倒したこともあり、2時間21分 54 秒で17 位に終わった。だが、2回目のマラソンとなった 一昨年の別府大分毎日で2時間11分 48 秒と、マラソンラン ナーと言えるタイムを出した。
ハーフマラソンのベストは2013 年の丸亀で記録した1時 間2 分 43 秒と平凡なタイムだが、山本はその後ハーフマラ ソンを走っていない。5000ｍの自己ベストは2010 年に記録 した13 分 45 秒 43で、2015 年のゴールデンゲームズ inのべ おかでは13 分 45 秒 75とその記録に迫った。2015 年の11月 末に行われた八王子ロングディスタンスの10000ｍでは27 分 55 秒 40と、自己ベストを大幅に更新した。2015 年以降の 全日本実業団駅伝では７区、５区、５区を走り、必ず区間３ 位以内を確保している。
2016 年11月、ニューヨークシティ・マラソンでは自己ベ ストにあと1秒と迫る2時間11分 49 秒をマークし、同大会 日本人最高順位となる4 位入賞を果たした。このレースは 山本にとって実質的には大幅な自己ベストと言っていい。
第１にニューヨークシティのコースは山本が自己ベストを 記録した別大のコースより起伏に富んだ、はるかに難しい コースであること。第２にニューヨークシティの出場選手の レベルは、東京以外の日本のマラソンのレベルをはるかに 超えていること。東京は今年から高速コースに変更となっ た。ニューヨークシティで2時間11分台を記録した山本な ら、2時間10 分を切ることも可能だろう。
