Watch: England's Norton's scorching 33kmph try, while USA's Isles clocks 34kmph

England’s Dan Norton and the USA’s Carlin Isles are renowned as two of the fastest men in world rugby.

Both of them have lit up the sevens scene for a number of years now with their searing pace and abundance of tries. Both men were on form this last weekend in Las Vegas, taking advantage of the dry and fast conditions, as the USA were crowned champions for the second year running, and topped the series rankings.

England beat Fiji in the battle for fifth place after crashing out in the quarter-finals against Argentina. However, before facing Fiji, they came up against Australia, where they won 33-14. Norton was on the scoresheet in this game, scoring his 320th try, and racking up an impressive 33 kmph as he ran in from his own half:

While this was impressive from Norton, Isles went a step further en route to the final in Vegas. Playing New Zealand in the semi-final (who were leading the series going into the tournament), Isles was clocked at 34 kmph as he scorched round the outside of the Kiwi’s defence:

At the halfway point of the season, Mike Friday’s USA are setting the pace, which is no surprise when they have speed to burn from the likes of Isles.
