Lee Grantham Maps 5k Run Plan to Cut Five Minutes

A 5k run for men in their 40s can sit around 24 minutes, but Lee Grantham says the right programme can strip five minutes off that time. He paired that benchmark with a nine-week structure built around controlled intervals, easy running and recovery between hard sessions.

Lee Grantham and the 24-Minute Mark

Running Level data puts recreational male runners in their 40s at around 24 minutes for 5K, a useful reference point for anyone trying to judge where they stand. Grantham, a running coach, says the gap to the next level is realistic if the work is organised properly.

“What we put in between is the recovery runs and easy runs that accelerate the recovery,” he said in a YouTube video. The line cuts to the heart of the plan: the hard sessions are only one part of the week, and they are designed to stay controlled rather than all-out.

Grantham’s Three-Phase Work

The structure starts with 12 x 500m and 60-second rest in Week 1, then moves to 6 x 1k in Week 2 and 3 x 2k in Week 3, with a Sunday 12-14k conversational long run alongside the work. That opening block is built to layer volume without turning every session into a race.

The middle phase raises the load again. Week 4 calls for 14 x 500m, Week 5 for 7 x 1k, and Week 6 for 3 x 2k plus 1 x 1k, with another Sunday session of 6 x 1k Zone 3 efforts. By then, the runner is being asked to hold pace for longer reps while keeping the same 60-second rest.

From 16 x 500m to 3 x 2k

The final phase pushes the interval count higher still. Week 7 jumps to 16 x 500m, Week 8 to 8 x 1k, and Week 9 to 4 x 2k, again with 60-second rest. The Sunday long run closes with 3 x 2k Zone 3 efforts.

That progression gives runners in their 40s a concrete target and a road map. The benchmark says 24 minutes is a reasonable average for recreational men in that age group, while Grantham’s plan says a five-minute improvement is within reach if the runner keeps the easy days easy and the recovery work in place.
