What race directors say

"My compliments to your product and service. I have used RaceClocker for several events, and I have to say - I LOVE IT! Your program has made timing rowing head races very easy. It is easy to use, accurate, and probably the best feature is live results."

Gregg Hartsuff

Head Coach University of Michigan Men's Rowing

"We have been using RaceClocker for the past 4 editions of our annual ADR Regatta. Over the years we have seen it develop into a reliable and easy to use timing solution at very low cost. Among others live results and split times are what rowers enjoy at our event."

Giovanni Margaroli

Race Director ADR Regatta

"Thanks for a wonderful tool. We started using RaceClocker recently for our annual events as an upgrade from stopwatches, pen and paper and Excel sheets. It works smooth, simple, intuitive, accurate and easy. We spend a lot less time on post-race calculation and the live results are a bonus."

RaceClocker key features

Import start list

Upload an Excel file or copy/paste your participant data from any other app to build your start list with no effort. Our import feature supports categories, wave starts and other meta data.

Time anywhere

Start, finish and split points of your race can be at any location. RaceClocker is cloud based and timing is managed from the timing dashboard. Timekeepers in the field can use any smartphone, tablet or laptop either online or offline.

Correct mistakes

RaceClocker includes multiple options to fix timing errors. Accidental timings can be 'undone' or assigned later to another participant. A full history of time stamps is kept. Backup timing data can be manually added at any time.

Time trial, waves and mass start

RaceClocker is great for time trial races where participants start one after another. Or for races where a wave or 'flight' of participants starts at the same time. Mass start races are also supported.

Live results

Results are published in real time so the crowd can follow along, either online or at the club house. Results are optimized for live display at your venue and can easily be published and shared.

Publish and archive

All timing registrations as well as final ranked results can be downloaded as Excel file for your archive or for further processing.
