I talk a lot about physiological profiling, and how getting tested in an exercise physiology laboratory can be really helpful for refining your training. However, I also know that many athletes do not have access to exercise physiology labs for this testing.

Accordingly, I’ve put together a couple of calculators on the Endure IQ website that you can use to get decent estimates of things like intensity thresholds using easy-to-access field test data.

In this section we are going to talk about the metabolic calculator. I’ll walk you through how to perform the field tests to get the necessary data. But we also include calculators for critical swim speed, functional thresholds power, and critical running speed.

#1: The metabolic calculator

Our first calculator, which you can find here, uses field test estimates of your VLa_max and V̇O₂max to predict your two lactate thresholds – which we use to determine training zones – and your Fat_max, or the intensity at which your highest rate of fa...

Field test estimate of critical swim speed

The Critical Swim Speed calculator needs to best paced time trials over 200 m and 400 m. This can be done within the same session, so it’s important to have a good warm up before the first-time trial and also ensure you...

Field test estimate of cycling functional threshold power (FTP)

If you’re a cycling, you have likely heard of FTP – which is an indicator of the power you can hold for an hour. We can use FTP to generate training zones, and we can estimate FTP using a 20-minute test. Our es...

Field test estimate of critical run speed: 5-km time trial

Our running field test is a 5-km effort – how fast can you complete 12.5 laps of 400-metre athletics track, although you can also complete the on your favourite flat running route. If you’re lucky enough to have...

In recent blogs and newsletters, I have extensively discussed 'within-session intensity regulation.' I believe that proper within-session intensity regulation is one of the most critical components of the training process. It's a topic I spend a lot of time contemplating, planning for, and researching.

But what exactly do I mean by 'within-session intensity regulation'? In this blog, I'll attempt to clarify this concept.

Context

Imagine you're training for an Ironman. You're currently in the midst of a four-week Specific Strength training block, focusing on (i) accumulating a substantial overall training volume and (ii) engaging in long, tempo runs on hilly terrain. Your training program emphasizes low-intensity sessions below the lactate threshold, allowing you to train extensively and frequently without inducing excessive fatigue (7, 8). The only sessions in your plan that exceed the lactate threshold are (i) a midweek trainer workout involving 8-minute thr...

If any of you have listened to Dan’s chat with Triathlon Taren on his podcast recently, you would have heard him talk about the importance of getting your zone 2 intensity right and ensuring that level 2 endurance training is at the correct physiological stress, i.e. below the first ventilatory (or aerobic) threshold. The reasons that this is so important are both from an adaptation perspective (i.e. ensuring we are making the correct physiological adaptations), but also from an overall physiological stress, which effects our ability to train consistently well. This blog discusses why ensuring that your level 2 training is actually at level 2 could be the key to unlocking your ability to train consistently as you pursue your Long Distance Triathlon goals.

Indeed, one of the most important factors impacting the success of training for long-distance triathlon is intensity distribution and discipline, concepts we will cover in great detail in Endure IQ LDT102: Training Program Fundamenta...
