Halmer Harrier Diane Morris finished as third overall female at the gruelling Sublime Twenty4 Ultramarathon at the weekend.
Morris completed an incredible 80 miles at the event, which saw competitors take on 6.7 mile loops of the same course in a 24-hour window from 12pm on Saturday until 12pm on Sunday.
The Spalding athlete ran through the night with no sleep or major rest stops, just a week after running the Lakeland 50 ultra event.
Fellow Halmer Harrier Steve Tucker managed 47 miles with five hours of sleep, while Rob Hammond completed 40 miles but saw his progress curtailed by an ankle injury after ten hours.
He could only walk after sustaining the injury and managed just one further lap.
Two other distances were contested at the event, with the Harriers represented in both.
In the 5k event, Sonia Lawrence (41.51mins), Jo Jacklin (42.23mins) and Teresa Lee (48.19mins) all finished in good time.
For Lawrence and Lee, it was their first-ever 5k event.
In the 10k distance event, Marie Sampson was the second placed female overall in 59.32mins. Phil Reed (1.08.07hrs), Tim Baxter (1.09.30hrs) and Katie Baxter (1.18.59hrs) were the others to take part.
