There are no official records of distance/speeds for players. Most found on the net and in the media are unofficial. In general players running in a straight line are not often found to accurately time stamp them. However, recently #Toderai Chavanga did 10.27 seconds 100m. And there is a formal record for Nigel Walker a former Welsh winger who ran 100 meter hurdles as well as playing Rugby and he was recorded as 10.38 over 100 meters by the Olympic body. Its suspected that many people will have their opinion on who actually is the best but without independent records its very difficult to say
