Rock n Road Runners Thursday Intervals: Lactate Threshold alternations

April 18 at 6:00 pm - 7:00 pm


This is a 60 minute group run focused on building strength, stamina, power and speed through interval-based training.

This session is lead by fully-qualified run coaches Dan & Rik and entails a thorough warm up consisting of easy running, mobilisation work, dynamic stretching, drills and strides. This warm up also focuses on improving various aspects of run technique, biomechanics and efficiency. Not will interval training improve your performance at all distances but it’s a really fun and social way to train. Anyone and everyone can benefit from interval-training regardless of experience level or goals.

The main set is usually interval-based, meaning that there is some faster-paced running for a set time or distance, interspersed with recovery which is either easy jogging, walking or standing. The aim of each interval session is to improve a certain aspect of our physiology, such as our pace at Lactate Threshold, Vo2 Max or increase our Running Economy and Neuromuscular Efficiency.

These sessions are also individualised for each attendee as we regularly carry out 3k and 5k time trials (or use a recent race result) to ascertain pace zones for different running intensities. This allows you to run at the right effort and avoid overexerting and overtraining.

The first session is free and all subsequent sessions are £5, unless you are a member of the Rock n Road Runners run club. If you would like to join the club click here or email for more info.



– Warm Up: Easy jogging, mobilisations, drills

– Strides: 4-6 x very short bursts of speed

– Main Set: Lactate Threshold alternations

4-5 x (4mins slightly faster than Lactate Threshold effort / 4 mins slightly below Lactate Threshold effort)

Lactate Threshold effort is an intensity you could hold for 45-60 mins. Around 8/10 RPE. Breathing is deep and laboured. Think comfortably uncomfortable.

Slightly faster than LT pace might be closer to 10k effort for most and slightly slower nearer marathon effort.

There is no recovery between intervals so don’t run the faster reps too hard otherwise you’ll slow down too much on the slower reps

The aim of the session to produce lactate and other metabolites when running faster and learn to shuttle and utilise these products during the slower efforts. These adaptations should allow us to run at faster paces for longer.

– Feel free to carry out your own cooldown. This won’t be included in the 60min session
