Members of Skegness and District Running Club have been taking on a series of events.
The Belvoir Challenge starts from Harby Village Hall and runs through the Belvoir estate.
There are many stiles to negotiate as well as hills and muddy farm tracks, footpaths and bridleways.
Steve Langford and Andy Shelton tackled the 15.7-mile route and Steve dug deep to finish in a time of 2:39-14 for 135th position out of 455 finishers.
Andy ran with Steve for 10 miles before pushing on and using this as a good training race in his marathon build-up, finishing in a good 2:24-16 for 85th position.
Curtis Jones took on the 26.2-mile, finishing in 142nd place in 5:07-01.
Member Melanie Standbrook travelled to Leicestershire to take on The Beast, an off-road event held at Aylesford Equine Cross Country Course.
With approximately 40 jumps to tackle, two water splashes, camouflage netting to squeeze under, lung busting hills and even a couple of waist-deep water wades this was a tough course.
There was a one-lap and two-lap option and Melanie opted for the 10-mile two-lap event, finishing in 1:50-17, the seventh lady.
The Cleethorpes Promenade 5k saw six members compete.
Stuart Cragg clocked 17-39 to finish as first veteran and take seventh place overall.
Mark Simons ran well to finish in 21-46, only about 45 seconds outside of his personal best.
Helen Blair took 1 min 48 secs off her best time for a finish of 22-10.
