Four members of Bicester Triathlon Club have recently participated in marathons across the country.
Joanne Hooks completed the Shakespeare half marathon in two hours and six minutes while Mark Burrows conquered the Blackpool Marathon in three hours and 55 minutes.
Matt Holman and Debbie Gilbert took part in the London marathon.
Mr Holman has so far raised more than £4,000 for the Multiple Sclerosis society and there is still time to donate.
He chose the charity because his wife, Kirsten, who has completed multiple long distance triathlons herself, was diagnosed with relapsing remitting Multiple Sclerosis.
The diagnosis came after she had experienced severe headaches and sudden loss of vision.
After previously finishing Ride London and Swim Serpentine, Ms Gilbert also earned the London Classics medal.
