These events are swim / run races. They are all in a mixture of heated & unheated water.
There are 2 distances available at each of the 4 races - Main race - 750m swim & approx 5k run, or the shorter option - Super Sprint consisting of a 400m swim & approx 2.5k run. Currently Races 1 & 3 are at Hillingdon Sports & Leisure Complex and are 750m/400m swim in the outdoor pool followed by an approx 5k/2.5k run on grass. At Hillingdon Sports & Leisure complex, the swim is a 'Snake Swim', all swimmers going off at 20" intervals depending on their predicted swim speed to complete 15 lengths of the pool. The run is an out and back course, giving competitors plenty of opportunity to see the position of their opponents. This also gives your families plenty of opportunities to cheer you on!
