Tokyo Marathon Guide: What You NEED to Know Before Race Day

This is the Tokyo Marathon guide I wish I had. I ran it in 2025. And even though it’s an incredible race, there are things nobody tells you. From confusing cutoff times to the toilet chaos, packed aid stations, and what layers to wear, I’ll walk you through everything you need to know before race day. If you're preparing for the Tokyo Marathon, this guide will help you avoid stress, stay on pace, and run your best. I’ll explain how to get in (even if the lottery feels impossible), what to expect at the expo, how the course feels, what to bring, and what can trip you up on the day itself. 🕒 Timestamps: 00:00 – Hook: My most stressful toilet moment 00:46 – How to get into the Tokyo Marathon 01:24 – Expo tips and transportation 02:06 – Cutoff confusion and race clock timing 02:53 – Crowded start and pacing advice 03:12 – Runami 03:51 – Aid stations, Pocari Sweat, and fuel plan 04:50 – What to wear and throwaway layers 05:41 – Toilet struggles and how to avoid them 06:34 – Course layout and finish area tips 07:21 – Recap and best prep tips 📱 Follow me on Strava: https://strava.app.link/ibEKbNwxhSb ✉️ Reach me at: [email protected] 📘 Try Runami, my AI running coach with a free 7-day trial: https://runami.com 🔔 Subscribe for weekly videos on marathon tips, training advice, and race-day prep. #TokyoMarathon #MarathonTips #RaceDayPreparation
