Synchronise and command your Race Clocks – Raceclock commander

Recently a friend of mine crossed the finishing line of the 2019 Boston Marathon. I was proud of his achievement and we decided to purchase the finishing-line photo. The next day when he received the result of his race, we realized that the time on the clock did not match his race time. The clock indicated a finished time was approximately 20 seconds slower than the actual time he completed the race in. 


What went wrong? 

The RFID chip timer was correct but the race clock had been set manually and was 20 seconds behind the actual timer. His estimated finish time was 3:56:15 compared to a gun time of 3:59:35. While other runners had issues as a result of the weather’s effect on the equipment and timing chips, his problem came down to timing issues.

What’s the big deal? 

For runners or anyone in sports timing events, the time recorded in each race is the driving factor that causes them to push to the next level. We work harder to get better from our previous records. It indicates growth and progress that we are getting better each time. But it’s unfortunate that we’ve learned that even the most organized race can be flawed when they fail to address the timing issues. Trying to set the clocks manually for multiple wave race is like inviting the inevitable. 

So, I tried to explore possible solutions to synchronized race timing, automation and a cheaper alternative to what is available in the market. I found out that there is a program with FREE software that can synchronize your multiple race clocks in seconds. It handles the complete automation of multiple heats remotely using the radio frequency and it’s affordable. That system is called Raceclock Commander.

What solution does Raceclock commander offer?

Still, all hope isn’t lost because Raceclock commander is dedicated to providing accurate and precise race timing solutions to all race clocks series (  Ultra Bright LED, Flip Digit and Rugged Series) or older versions. It works well with OM and XL series clocks with the remote control port. 

It is weatherproof. The setup has preset and manual configurations. The radiofrequency feature enables a drive-through setup.  

Hence, race directors no longer need to go through the process of resetting these clocks for each wave. This system accurately syncs race clocks and you can remotely control and sync the race clocks through a computer.  

Race organizers and administrators can now set and program multiple race clocks to work on the same clock but different heat or different time and heat precisely.
