The 5K Simulation Workout
This is a classic Frank Horwill (a famed British coach who formulated the Five Pace Training Theory used by many great athletes such as Sebastian Coe and Said Aouita) workout which I’ve found very useful in simulating the deep gut, lactic pain of a 5K.
It’s not so much the pace that makes you have to dig deep but rather the very short recovery time in between reps. You have to stay very focused on each rep to keep the pace fast and hard. If you finish the workout feeling fine then you’ve run too slow. If you finish feeling tired and unable to do more then you nailed it!
Warm up for 15 to 20 minutes
7 x 800m with 30 seconds recovery (trying to run 5K pace for the entire run)
Cool down for 15 to 20 minutes
I’ve run this when I was very fit and knew I was ready to race when I could complete this workout successfully by hitting all my splits. It’s a great workout to have a partner in if you train with someone of the same ability. That will help to ensure you can keep pushing hard right to the very last step. Going out too fast will have you slowing down a lot towards the end because there will be too much of a lactic acid build up so make sure you start at a pace that you are ready for.
I’ve personally completed this workout only a handful of times and only when I know I’m very fit. I used the workout to build a lot of confidence so I could go into 5K races knowing I would be able to handle a constant fast pace.
