Keith Flint died just days after splitting from his DJ wife, putting his house up for sale, and running a 5km race only 48 hours before he died.
The 49-year-old musician was found dead at his country mansion near Dunmow, Essex, and his band mates later revealed he had ended his own life.
This afternoon a photograph emerged, believed to be the last of the star, looking fit and well as he ran the Chelmsford park run in a personal best time of 21 minutes 22 seconds on Saturday morning.
Fellow runner, journalist Rob Hadgraft, tweeted the picture and wrote: "Sad news about Keith Flint – comes only two days after he'd looked in great shape and spirits, storming round the Chelmsford Parkrun in a PB."
