You guys asked, so here it is. A walk through and explanation of analysis between ‘Athlete A’s’ two lactate threshold tests, 6months apart. If you have any questions, let us know!

Endurance training isn’t only about putting in the miles, being strong enough to put them in week in week out until you realise the improvements is key. That’s why every athlete we coach gets more than a training plan. You get direct access to our in-house physio and sports therapist, fully integrated into your coaching, not bolted on as an afterthought.

How it works? Your endurance programme is built around your goals, life, and current physiology. Niggles get flagged and assessed early by our in-house sports therapist, catching them before they become setbacks. Targeted prehab/rehab work to fix what’s flagged and bulletproof what isn’t is built straight into your plan. Strength and conditioning closes the loop. It’s built on what the assessment and rehab work uncovered.

This all feeds back into your coaching, continuously adjusted, session by session. Performance based coaching: one team, one plan, no gaps between your training and your recovery.

Very proud of the team over these last few weeks. Results have been flying in and it makes us incredibly proud seeing how our athletes have got on at their events.

Sub 10 Ironman at Roth for Dave after a short run in with the main focus on having been on the 70.3 distance this year.

A career first for me as a coach to have an athlete placing on the overall podium and 1st in AG at the European standard duathlon championships in Banyoles for Veronica. This is only the first of 2 races whilst she’s out there competing with the middle distance race next weekend!

Ben put out a great debut performance over the middle distance at the Cotswold Classic. With limited training hours available, a busy family/work life, and being new to the distance, this was a great way to kick off his middle distance journey.

Coach Henry raced this Croyde triathlon in the build up to Embrunman in 5 weeks time. A suitably tough course to test the legs after a solid training week, showing good signs in the lead up to what is going to be a challenging day in Embrun over the full distance posting an overall win by over 10mins.

A recent testimonial we received from Harro after working with us up to his debut Ironman in Austria last year. We strongly believe in adaptability, communication, and education, alongside the programming basics when coaching an athlete in order for them to reach their potential.

We have a couple of coaching spots available so please get in contact if you’d like to have a chat.

Almost too many results to fit on the page, that’s how you know racing season is well and truly upon us! The team have been out at multiple events across the 10km and half marathon distance. Athletes running for difference reasons from PB attempts, to benchmark runs, race practice, or pure racing enjoyment.

If you’d like in on the action drop us a DM of head to our website. We’d love to hear from you.

The 10% rule for runners. A very useful guideline and it drills in good training principles…however, dramatic single session increasing compared to previous history poses the biggest risk. When progressing training, do so sensibly, find the minimal effective dose to yield improvements. Focus on the long term.

A few of our athletes had a good midweek hit out at our local timed swims last week. The team smashed it across the varying distances, with it also being Sarah and Marks first open water swim of the season! In our opinion these timed swims are invaluable for our athletes. Do you practice in the open water?

Last weekend was a big weekend for a few of our athletes, taking on a couple of different half distance triathlon events. Both Rob and Will at the Cotswold 113, a great local event, and Dave taking on the European scene in Warsaw.

Some serious hard work has gone in from all three of the guys for these events, all of them at different stages in their triathlon journeys. Will’s first half distance, posting an incredible 2:34 bike split on a road bike. Rob using this as a prep race for Outlaw Full, taking an hour off his current 70.3 PB in the process. Dave looking to further develop his performances when already putting out some super strong times, resulting in his most well rounded 70.3 race to date with improvement across the board.

As always, there was lots of useful takeaways for everyone. With all of them invested in the long game, there’s plenty more improvement to come!

These are the weekends that get you fired up as a coach, with athletes racing far and wide at multiple events. A mixture of half marathons and 70.3 distance events. Good luck to all of our athletes racing and those racing at other events this weekend!

Why does lactate testing matter? What is it, what does it tell us, and common misconceptions.

As we cover in this post. Lactate testing/data is not the only metric you can use when dialling in your training, however it helps build that physiological picture alongside the other metrics (pace, power, heart rate).
