流山ロードレース大会に2年ぶり8回目の出場を果たし、無事に10kmを完走できました!
Read the original on note“Next time, I would like to run on a clear day!”
The runner took part in the 10km race and walked to the station in light rain. The two climbs and descents in the second half were difficult, but the runner ran with the encouragement of the spectators. The clean arena and efficient bag drop operation also helped reduce race-day stress.
