유튜브 「런닝인사이드」(예전 강씨TV)를 운영하는 러너가 직접 만들었습니다.
개인 Best time 3시간 38분, Sep 5, 2026철원 DMZ 마라톤에 나갑니다.
I started this because I kept missing the registration deadlines for competitions—I couldn't participate in the Inside Lawn or the Lotte World Tower competition because I didn't even know they existed.
왜 만들었나
Competition information is scattered. Organizer's website, registration agency, cafe announcements, Instagram —
It is also common for the dates and entry fees of the same competition to be listed differently.
정작 접수가 열리는 날은 아무도 알려 주지 않아,
It keeps happening that I miss out on the competitions I wanted to participate in.
그래서 런닝인사이드는 We gather and display it, and notify you when it opens. 일만 합니다.
