Completing a 5K race (5000 metres) is within the reach of many athletes in a few weeks, whichmakes this challenge very motivating. Once you've completed the challenge, you'll want to do itagain, and then improve your time. Here are some tips on how to do this effectively and some ideasfor iFIT series to train in.
A diversified training plan
To break your 5K record, it's best to incorporate a variety of exercises into your training plan:
● Practise high-intensity split running to be able to run faster for longer: the point is toprogressively push back your anaerobic threshold, i.e. the limit at which the body no longerhas enough oxygen to metabolise lactic acid, which generates losses in performance.
● Occasionally run shorter and longer races than 5K, e.g. 2 km and 10 km: this will improveyour maximum aerobic speed (MAS) and endurance.
● Strengthen your legs by running on an incline and doing bodyweight exercises: running onflat ground will seem increasingly easy after these exercises.
● Try the fartlek: this fun exercise consists of varying speeds and durations done at will duringa given time, to work on speed, reactivity, endurance and to strengthen muscles andtendons.
● Incorporate sprints into your runs, e.g. 80 metres of sprinting every 5 minutes: this explosiveexercise builds physical and mental stamina, while improving stride efficiency. Also, groundcontact time is reduced, which is one of the keys to achieving better running times.
Tips for improving your 5K time

These tips should also save you precious minutes for your next 5K:
● Don't forget the warm-up, for optimal physical and mental preparation for the race.
● Study the terrain: If you know the location of your next run, train by simulating real runningconditions by entering your route on the iFIT app. The real terrain data is transmitted to yourtreadmill, which automatically tilts, thanks to the coupling between iFIT solutions and GoogleMaps.
● Do not start too fast, manage the beginning of the race well and distribute your efforts: runin a negative split, with a more sustained pace in the second half of the race.
● Eat your last meal 2 to 4 hours before the race at the latest, so as not to be slowed down bydigestion.
● Plan rest periods between sessions and remember to stretch to promote muscle recovery.
