The popular fundraising event took place at the Sports Park in Cross Levels Way.
Runners took part in three different events throughout the day, a 3k, 5k and a 10k.
With a minimum fundraising target of £50, the event raises funds for ‘world-class research’ to help beat more than 200 types of cancer – including bowel cancer, breast cancer, prostate cancer, lung cancer, testicular cancer, brain cancer, children’s cancers and leukaemia.
Lynn Daly, the charity’s spokesperson for Sussex, said: “No matter how cancer affects us, life is worth racing for.
“Sadly nearly 1 in 2 of us will get cancer in our lifetime but all of us can help beat it. We’re proud that Race for Life has already helped double survival rates in the UK.
"Every penny raised at Race for Life truly makes a difference and powers progress."
