About Us

Welcome to RunPaceTools! I'm a local citizen runner based in Bangkok, Thailand, passionate about both road and trail running—from 5K races to ultra trail 100K adventures. I created this website to help myself and the running community easily calculate pace, time, splits, VO₂max, and more.

As an active member of the Bangkok running scene, I understand the needs of runners at all levels. Whether you're training for your first 5K or preparing for an ultra marathon, these free tools are designed to make your running journey easier and more enjoyable.

My goal is to share useful calculators and guides with fellow runners and to support the growing running communities in Thailand and beyond. If you find these tools helpful, please share them with your friends and clubs!

Happy running!
