Relay Judging Platform



Colorado Time Systems’ Relay Judging Platform technology is the most accurate way to judge relay exchanges, and provides a fair start to hearing impaired athletes.

When attached to a swimming start block the Relay Judging Platform is designed to detect swimmers who leave their blocks early.  The relay judging platform can also be used as a training tool to measure start reaction times, take-over times etc... (when used with a Colorado Pace Clock Pro).

Relay judging

Colorado Time Systems’ Relay Judging Platform(RJP) technology is the most accurate way to judge relay exchanges.The RJP allows your CTS timer to automatically compare the incoming swimmer’s finish on the touchpad with the departure of the swimmer leaving the starting platform.The RJP will provide the necessary information to judge a relay exchange to 1/100th of a second.

The NCAA has declared that automatic relay judging is the fairest and most accurate way to judge relay exchanges. All Division I NCAA Championships must use electronic relay judging..

Start reaction time

On every start, the RJP senses when the swimmer leaves the block and compares the time to the start impulse from the starting system with 1/100th of a second accuracy. Start reaction times can then be displayed on the scoreboard, with a CTS System 6 sports timer, at the beginning of the race.

Elegantly engineered

Both the top and the leading edge of the RJP are sensitive to the swimmer’s departure. Extensive research and elegant engineering allow the Colorado Time Systems' RJP to decipher between weight shifts and when a swimmer actually leaves the platform.


LEDs across the front of RJPs equipped with Speedlights flash simultaneously with the start tone and strobe light. All athletes benefit from the visual signal, which they can easily see without altering their race-ready posture and train for the fastest reaction time humanly possible. Backstrokers will benefit from the visual start signal inches away from their eyes.

These are the RJPs used at the NCAA Division I Championships, which Rowdy Gaines of ESPN described as “space age starting blocks.” “I’m impressed with the reliability of CTS's take off pads; they’re the best way to ensure fair relay judging.There’s no question that training with CTS’s RJPs has helped us improve our relay exchanges, and training with the Speedlights has made us quicker. off the blocks.” - Auburn University Head Coach David Marsh

Mounting Options:
Mounting is simple; a double strap with a through buckle allows quick set-up and easy removal, and is compatible with most Starting Block manufacturers. Certain Starting Blocks require customized RJPs.
