Mary Campbell and Persephone Hagan, both members of Chichester Westgate Triathlon Club, competed at the World Triathlon Championships in London.
They represented GB in their respective age groups having both qualified for a place in the national team at the British Triathlon Championships in Liverpool in July.
Race day started at 5.45am and thousands of international athletes were busy preparing bikes and running shoes for quick transitions, from swim to bike, and 40k later, from bike to run.
Because of the low air temperature, the swim was reduced from 1.5k to 750m, followed by a sprint of about 600m to the bikes.
The bike leg offered the chance to take in the sights of London as they cycled on closed roads - two 20k loops, going past Buckingham Palace twice per loop, Big Ben, The Cenotaph, The Mall, and through Wellington Arch.
Another 600m run with the bike preceded a final 10k.
Campbell finished the race in 2hr 12min 17sec, taking 33rd place out of 117 in the age group 35-39, while Hagan came in at 2.22.20, finishing 54th out of 108 in the 45-49s’ group.
Within a week of the world championships, Campbell went on to qualify second at the Anglia Water triathlon for a GB place at the 2014 European Championships in Kitzbuhel.
