The pace on these LumaLanes is set to 30 seconds per 50 yards. The LED is spiraled a bit on the floor, but the light is still plenty visible. The swimmer mentioned "LumaLanes keeps me really accountable during practice! I can't do a fast set and then zone out for a set or two like I normally do. LumaLanes keeps me accountable every single lap." They also went on to explain "...it also motivates me more in the middle of practice when I'm getting tired! Even though I'm exhausted, I subconsciously won't let the light beat me, causing me to push myself when I normally wouldn't!"
