Easy runs

Running coaches and exercise physiologists continue to assert that runners, for the most part, should do around 80% of their weekly runs at an easy pace, Runners World, Part of the Hearst UK Wellbeing Network long runs.

Tempo runs

or ‘hard but controlled’ runs and generally fall into one of two categories: steady running economy and running form. They’re sometimes described as threshold or ‘hard but controlled’ runs and generally fall into one of two categories: steady tempo runs of two to six miles, or longer tempo intervals London Marathon: A runner’s and spectator’s guide.

Here’s an example of a longer tempo interval session: 4 x 1 mile repeats at tempo pace, with two minutes of recovery jogging between efforts. You should do tempo runs no more than once a week and they should make up no more than 10-15% of your total training volume. Although your tempo pace should feel ‘comfortably hard’ and not be a flat-out effort, tempo runs are still hard sessions and you should respect the recovery period that they deserve.

VO2 max runs

VO2 max training helps you to become a more efficient runner and sharper racer. Although these sessions are most beneficial when you’re preparing for races at the shorter end of the spectrum, like a 5K, Tempo runs help to improve your half marathon. Generally, VO2 max pace is something that people can only sustain for up to about 10 minutes at a time.

Here’s an example of a VO2 max workout: 6 x 800m at VO2 max pace, with four to six minutes of recovery jogging between efforts. You should do VO2 max workouts no more than once a week and they should make up no more than 6-10% of your total training volume. When you do these workouts, you’re running at, or close to, 100% of your maximum oxygen capacity.

Speed form runs

Speed form runs are a type of interval session designed to boost your leg speed, as well as your running form and economy. They’re tailored to help you prepare for races of 800m up to 5K.

Here’s an example of a speed form workout: 8 x 400m at speed form pace, with three to four minutes of recovery jogging between efforts. You should do speed form sessions no more than once a week and they should make up no more than 4-8% of your total training volume.

Long runs are often done at a relaxed pace, so you can save your legs for other days of the week when you might do tempo runs or VO2 max runs. That said, your experience, ability and goals can influence how quickly you complete – and how much distance you cover in – your long runs. If you’re training for a race, remember to gradually build up your weekly mileage and train your body to keep going for however long the race is going to take you.

Put simply, if you want to run a marathon in 2:45, 3:29 or 4:11, for instance, then you should train to the point where you can run 10 repetitions of 800m in the same time: 2:45, 3:29 or 4:11. The only difference is that your marathon time is hours:minutes and your 800m time is minutes:seconds. While you shouldn’t take Yasso 800s too seriously or literally as a marathon race time predictor, they still provide a great workout.

Yasso, who has unofficially been known as the ‘Mayor of Running’, suggests doing Yasso 800s once a week as part of a marathon training block.
