Lactate Testing Services

Stop guessing your limits. Measure them, then train with intent!

Objective lactate testing reveals exactly where aerobic efficiency ends and fatigue begins, defining what’s sustainable, what’s costly, and where adaptation happens so you can train at the right intensity for sustained performance on climbs and long efforts, and ensure your training works for you, not against you 

STANDARD / BEST VALUE - TRAIL LACTATE PROFILE

£80–£100 | 60 minutes

A trail-specific lactate test designed to identify your key physiological thresholds and translate them into practical training and race-day guidance.

Using an incline-based treadmill protocol and the Arkray Lactate Pro 2, this test focuses on what actually matters for trail and ultra running: sustained climbing efficiency, pacing control, and fatigue resistance.

What’s included:

• Progressive incline treadmill lactate test

• Measurement of blood lactate, heart rate, and perceived effort

• Identification of:

  • 1. LT1 (aerobic threshold) – sustainable “all-day” effort

    2. LT2 (lactate threshold) – upper climbing limit

• Clear training zones based on incline and heart rate

• Written summary with key results and recommendations

Best for:

• Trail and ultra runners

• Athletes struggling with pacing on climbs

• Anyone wanting objective intensity guidance beyond “feel” or pace

Seasonal Block Package

£180 | 2 tests over 8–10 weeks

Track how your training is working, not just how hard it feels.

This package includes two identical lactate tests using the same protocol, allowing direct comparison of physiological adaptation across a training block.

What’s included:

• Baseline lactate test

• Follow-up retest (8–10 weeks later)

• Side-by-side comparison of:

  • 1. Lactate at given inclines

    2. Heart-rate drift

    3. Threshold shifts

• Practical guidance on how to adjust training intensity going forward

Best for:

• Structured training blocks

• Pre-season or mid-season performance checks

• Athletes who want evidence their training is working

Ultra Prep Package

£250–£300 | Performance-focused support

A comprehensive package aimed at ultra and mountain runners preparing for a specific event.

This goes beyond testing alone and focuses on race-relevant execution.

What’s included:

• Full trail-specific lactate test

• Threshold-based uphill pacing guidance

• Identification of sustainable climb intensities for long efforts

• Discussion of race strategy (where to sit below LT1, where LT2 is acceptable)

• Optional discounted follow-up test closer to race day

Best for:

• 50 km to 100-mile trail races

• Mountain or hilly ultras

• Athletes who want confidence in pacing before race day

ℹ️ Important Notes

• This is performance testing, not medical diagnosis.

• Results are most valuable when tests are repeated consistently over time.

• Testing is suitable for runners who can safely run or hike on a treadmill at incline.
