Are there 5K or shorter races in Bangkok?

When is the running season in Bangkok?

The events listed here fall in February and November. Plan a training block backwards from whichever of those suits you.

What is the weather like for the Amazing Thailand Marathon Bangkok?

In February, Bangkok averages a daily high of 32.2°C and a low of 23.5°C, with rain on about 19% of days. That is warm enough to cost you real time, so start conservatively and drink at every station. Figures are a ten-year average of recorded conditions for that month, not a forecast.

How do I enter a race in Bangkok?

Entry opens on each organiser's own site, and fees, closing dates and start times change every year. Each race above links to its own page here, which covers the course, the conditions and how to train for it, and points you at the organiser for the current year's entry details rather than repeating a number that may already be out of date.

Why are exact race dates not shown?

Race dates move every year and a stale date is worse than none. The month each event is normally held is listed instead, which is what you need to plan a training block. The organiser's site carries the confirmed date once it is announced.

What distances can I race in Bangkok?

Across the 2 events listed: Marathon, Half marathon, 10K, 5K. Pick the distance first and the date second — the build-up a distance needs is what decides which month is realistic.

How long should I train for the Amazing Thailand Marathon Bangkok?

Allow 16 to 20 weeks from a base you already hold, not from scratch. That is the marathon standard, and it assumes you can already run comfortably three times a week before the block starts. The race page for each event breaks the build-up down further.

How far in advance should I enter?

The larger city marathons fill within days of opening, or run a ballot months ahead; smaller 10K and 5K events often take entries until race week. Check the organiser's site as soon as you have picked a race — entry timing is the one thing you cannot make up for later in training.

Can I run these courses outside race day?

Mostly yes, and it is worth doing. City-centre courses use public roads and parks that are open year round, so you can run the closing kilometres as a training session and know exactly what they feel like. The mapped Bangkok routes are a practical starting point for that.

Where can I train for these races in Bangkok?

The 10K and long-run routes mapped for Bangkok use many of the same roads and paths these courses do, so they work as course reconnaissance as well as training. Each race page also lists how long a build-up the distance needs.
