That’s why tempo running isn’t a set pace. Yup, you heard it… tempo running is not a set pace and the reason for that is let me create a scenario for you. If your 10 miles personal best is 60 mins, 6min mile pace/3.40km pace, on a flat fast course with no wind. On your regular training week, it’s blowing of Gail and you’re on a trail/grit surface that’s slightly undulating with rolling hills. To hit that 6min mile/3.40km pace you will have to work so much harder in certain sections to achieve the set pace, so ultimately you’re now working harder than tempo pace and that isn’t the purpose of the session.
Tempo running is a sweet science where at a certain heart rate intensity where you get tested in a lab on a treadmill. You’ll run at set paces on the treadmill for just 3mins at a time with 30s-60s recovery, whilst the lab guy takes a small sample of blood from your ear or finger, you’ll jump back on at a pace 1kmph faster than the previous 3min stage until the lab guy sees a spike in your blood lactate. Usually, there is a small 1st spike called aerobic threshold then the 2nd spike is where your lactic threshold is. Even though you may have been running at 16kmph on the treadmill when that happened it doesn’t mean 16kmph is your tempo pace. You look at your heart rate value, it may say 168bpm, that’s your sweet spot where you body buffers and accumulates lactic acid at the exact same time.
So even when you’re running up a slight incline or into a headwind if you’re sitting at the right heart rate intensity then you’re in the right physiological zone called tempo running, where you’re sitting at the correct intensity to help your body cope and work with lactic acid.
I would usually put a tempo workout into my athlete’s running plan once per week during a phase where there are no races on the calendar to build a strong aerobic foundation for a big peak come competition time. Tempo running allows the body to buffer and use lactic acid at the exact same time, which during distance races is extremely beneficial.
When tempo running as done at the correct intensity you will feel the great fitness benefits from it. Your race times and interval training workouts.
Examples of tempo running sessions –
• 4 miles straight tempo
• 3x10mins tempo with 90s recovery
• 5 miles straight tempo
• 6x1mile with 45s recovery at tempo HR
Hopefully, this helps you understand the science of tempo as nowadays athletes throw it around as a sub-maximal interval workout, which it isn’t it is an extremely important part of your training and one of the only training sessions that aren’t done off of pace but off heart rate for maximum benefits.

I have also started a podcast on how to stay focused during this tough time “The Sean Fontana Podcast” on Spotify podcast, iTunes podcast and Castbox.
