Most runners train hard. Few train right. The Red Line Performance Club gives you the data, the programme, and the people to make every session count.

THE PROBLEM

You're not stuck because you're not trying hard enough.

You're stuck because you're training on estimates.

Your watch gives you a VO₂max score. It's a guess. Your training plan gives you zones based on race time. They're someone else's formula. Your easy runs feel easy. Your lactate curve says they aren't.

The problem isn't effort. It's precision. And precision starts with real data from your actual body — not an algorithm built for someone else.

That's what the Red Line Performance Club is built on.

WHAT IS IT

What is the Red Line Performance Club?

A data-driven performance programme for runners and HYROX athletes who want to stop guessing and start improving.

It's built around three things:

Real Data

Lab testing that tells you exactly what your body is doing — not what an app thinks it's doing.

Your Programme

Personalised programming built from your physiology, updated every 6 weeks as you improve.

Your People

A community of athletes and access to expert support — so you're never figuring it out alone.

Powered by Run Pace Pal — the training platform built specifically to turn lab data into structured, exportable training blocks.

WHAT YOU GET

Based on your current fitness — not guesses, not goal times.

HOW IT WORKS

Five steps. One system.

01

TEST

You come into Box Nutrition in Birmingham for your lab assessment. We measure your VO₂max, Critical Speed, and (on the Full Lab) your LT1 and LT2 through blood lactate testing. 75 minutes. Real data. Nothing estimated.

02

ANALYSE

Your results load straight into Run Pace Pal. Your 6 training zones generate automatically — all anchored to your actual physiology. We identify your limiter: is it your aerobic base? Your threshold? Your speed reserve?

03

TRAIN

Your first 4-week training block generates from your zones. Every session has a specific pace target. Every run has a purpose. Export directly to Garmin. Train with precision.

04

RECALIBRATE

Every 6 weeks you retest — a 3-minute and 12-minute Critical Speed effort, a 5K time trial, or a full lab retest. Your zones update. Your programme updates. You keep moving forward. No plateaus.

05

COMMUNITY

You're in the Red Line WhatsApp group with every other member. A group of athletes who take this as seriously as you do.

Jack is genuinely interested in my journey. The VO2Max results will help me control my blood sugars whilst doing strenuous exercise, safe in the knowledge that it is all science based - no guessing!

★★★★★

The session was fast paced and we were in and out in about an hour and a half. Jack talked to us the whole time, sharing some really interesting information. I have nearly 30 pages of information to go through!

LAUNCHING MARCH 2026

A test by itself is useless.

We've been testing athletes for years. Hundreds of VO₂max tests, lactate profiles, metabolic assessments. And we've learned one thing:

A single test tells you where you are. It doesn't tell you where to go. Without a plan built around your data, that report sits in a drawer. Your zones get forgotten. Your training stays the same.

That's why we built this. Not just a test — a system. Your lab results feed directly into personalised training zones, structured blocks, and a programme that evolves with you over time.

Every 6 weeks, you recalibrate. Every block builds on the last. Your plan isn't static — it adapts as you improve.

The Red Line Performance Club launches in March. Founding members lock in the lowest price it'll ever be.

ABOUT JACK

The person behind the data

I'm Jack. I have an MSc in Sports Science, I'm VDOT qualified, HYROX Level 1 certified, and I've tested hundreds of runners in my lab at Box Nutrition in Birmingham.

I played rugby until my body said no. When that ended I needed something — and running gave it back. But I couldn't find a training system that matched the seriousness I used to bring to training camp. Data, structure, measurable progress. So I built one.

I'm not the fastest person in the room. I'm the one who can look at your data and tell you exactly what's holding you back — and exactly what to do about it. That's a different kind of useful.

Every test at Box Nutrition is done by me personally. Every block reviewed. Every result explained.

FAQ

Common questions

For the lab testing — yes. Box Nutrition is in Birmingham B24. Most members travel up to 50 miles. It's a 75-minute test that sets your training for 6 weeks — most people find it's worth the trip. The Self-Guided plan has no in-person requirement.
Every 6 weeks you retest your Critical Speed using a 3-minute and 12-minute maximal effort, a 5K time trial, or a full lab retest. Your zones update from the new data. Your training block regenerates. No guessing — just earned progress.
The lab data makes your coach's job easier — they get real numbers to work from instead of estimates. Most coaches welcome it. If you're on a generic plan, the test anchors every session in it to your actual physiology.
You need to be able to run continuously for 20 minutes. That's it. The test builds gradually — you're not expected to sprint. It works at every fitness level.
Yes — Jack is in the group. Members share results, ask questions, and hold each other accountable. Guest expert sessions are announced there first. It's not a notification feed — it's a genuine community of people who take training seriously.
Yes — at any time. Self-Guided members can upgrade to Performance Club when they're ready for the test. Performance Club members can apply for One to One. Monthly plans can be cancelled at any time with no penalty.
