Speed record

A speed record is when someone does something really fast. It could be running, swimming, skateboarding - anything where you can measure how fast you go. The person who does it the fastest is the person who holds the record for that particular activity. For example if someone runs 100m in 10 seconds then they have set a speed record for that distance. To break the record someone else would have to run the 100m in 9.99 seconds or faster.
