Q: I had a question about the pool. I've got some intervals this week. It looks like the times my coach has set are based on yards. Is there an easy formula to convert those times to a meter pool?
A: To go from a 25 yard pool to 25 meter pool, you add 10 percent. For example, if your interval is 1:40, that's 100 seconds. Ten percent of that is 10 seconds. So, a 100 meter interval would be the 1:50.
Obviously, it doesn't work out to be that clean for all intervals, so you have to round to the nearest five seconds if you're using a pace clock. For example, someone on a 1:25 interval for 100 yards would come out to be the 1:33 interval for 100 meters.
