    June 16 – A Trifecta of Training: Base Run, Push Endurance & Bike Intervals

    Yesterday, Monday, June 16th, 2025, was a great example of a multi-faceted training day, layering different types of stimulus to build a well-rounded fitness profile for Hyrox. The day was broken down into three distinct parts: a long aerobic base run, a push-focused endurance strength session, and a quick, high-intensity BikeERG interval finisher. Let’s dive into how it all came together.

    A Quick Note on Volume & Intensity

    As always, the training I describe is tailored to my current goals and experience. It’s shared to provide insight and ideas, not as a direct prescription for everyone. Please listen to your body, scale appropriately, and prioritize good form and recovery. Consistent, smart training is the key to long-term success!

    Workout 1: Aerobic Base Run

    The first session of the day was a 63-minute aerobic base run. The goal was simple: maintain a steady, conversational pace around 5:50/km to continue building that deep well of endurance that is so crucial for events like Hyrox. This wasn’t about speed, but about accumulating quality time in Zone 2.

    My Experience: This felt good. I successfully held an average pace of 5:47/km for the 10.89 km, with a 10km time of 57:52. It was a solid, controlled effort that set the tone for the day without adding excessive fatigue before the strength work.


    Workout 2: Push Endurance Session

    Later in the day, I hit a time-crunched push workout. With only about 40 minutes, the focus was on high-volume supersets with strictly timed rest periods to maximize intensity and muscular endurance.

    The Workout Blueprint:

    My Experience & Training Intent:

    This session really burned! The goal was to use a light weight that I could push at a fast tempo to focus purely on muscular endurance. Based on my last push day, I selected weights I knew I could push for 20 reps without stopping. The first superset was tough; I did full reps on the main bench press, but by the time I got to the close-grip bench, I was pretty fatigued. I planned to use long-length partials for the close-grip portion as a good way to push past failure and get more time under tension. It’s a great technique to overload the muscle safely when you’re already tired. I’ll be increasing the weights slightly on the next similar session to continue the progressive overload.

    Scaled Options for Push Endurance:

    • Bench/Incline Press: Use dumbbells instead of a barbell for easier scaling, or use appropriate lighter weight.
    • Pushups: Perform from the knees or against an incline (like a bench or box).
    • Tricep/Fly Movements: Use lighter weight or resistance bands.
    • General: Reduce reps to 10-15 per set, or reduce the number of sets.

    Workout 3: Metcon – Max Effort BikeERG Intervals

    The day finished with a very short but very spicy metcon to completely empty the tank.

    The Workout Blueprint:

    • 5 Rounds:
      • 0:20 Max Effort BikeERG
      • 1:00 Rest

    Rationale & My Experience: This is a classic anaerobic power workout. The 20-second all-out sprint pushes your ability to generate maximum power. For me, this wasn’t about getting breathless; it left my legs, and specifically my quads, absolutely on fire. I could barely walk for a few minutes after the last interval, but it felt incredibly productive for building that top-end power and muscular resilience needed for a hard push in Hyrox.

    Overall Reflections:

    Today was a great example of how to layer different types of training. The long, slow aerobic run built the foundation. The strength session built muscular endurance and required a smart approach to weight selection for the intended stimulus. And the final interval session pushed the top end of my power endurance. Each piece complemented the others, contributing to the well-rounded fitness required for an event like Hyrox.

  • June 2 – The Value of Short Runs When Life Gets Busy

    June 2 – The Value of Short Runs When Life Gets Busy

    Today, Monday, June 2nd, 2025, was one of those days where the best-laid plans hit the reality of a packed schedule. I was shorter on time than I would have liked for a main session but really wanted to get a good run in. The original hope was to hit a more substantial strength workout in the afternoon, but unfortunately, work commitments completely took over, and that second session just wasn’t feasible. It’s a perfect example of the daily juggle we all face trying to balance fitness with work and life, and a good reminder that adapting our training to make the most of the time we have is a key skill for long-term consistency.

    A Quick Note on Volume & Intensity

    As always, the training I describe is tailored to my current goals and experience. It’s shared to provide insight and ideas, not as a direct prescription for everyone. Please listen to your body, scale appropriately, and prioritize good form and recovery. Consistent, smart training is the key to long-term success!

    Making Time Count: Adapting When Life Gets Busy

    Life inevitably throws curveballs at our best-laid training plans. Work, family, and unexpected events can make dedicating multiple hours to a workout seem impossible. It’s tempting to adopt an “all or nothing” mindset and skip training altogether if the “perfect” session isn’t achievable. However, for long-term progress, especially when preparing for demanding events like Hyrox or pursuing overall health, learning to adapt and make the most of the time you *do* have is a crucial skill.

    When time is short, or plans change, the goal isn’t just to do ‘something’ for the sake of it, but to perform a focused, quality session that still contributes to your goals. This might mean a shorter workout than originally planned, or one with adjusted intensity or volume, but one that maintains purpose. A strategically planned session, even if not your “A” workout for the day, can still provide a valuable training stimulus, help maintain routine, offer mental clarity, and keep your momentum strong. It’s about being smart and intentional with your available time, ensuring that even on the busiest days, you’re taking a deliberate step forward towards your Hyrox ambitions or general fitness targets.

    Today’s Trail Run: The Details & Intentions

    Given that my afternoon was unexpectedly filled with work, I made sure to get out for this trail run. The primary goal wasn’t to break records, but to get in a solid aerobic effort, enjoy some fresh air on the trails, and keep my heart rate primarily under 150 bpm. On trails with varied elevation, maintaining a specific heart rate zone sometimes means strategically walking the steeper pitches, which is perfectly fine and often a smart way to manage effort and stay within the intended training zone for aerobic development.

    The run ended up being **11.82 km**, completed in **1 hour, 20 minutes, and 55 seconds**. This came out to an average pace of around **6:51 min/km**. For me, this duration is a “shorter” long run, but a very valuable piece of aerobic work nonetheless.

    Why This Kind of Run Matters for Hyrox (and Life) – Especially Trail Runs!

    Even a run that’s primarily about “time on feet” at a controlled effort contributes significantly, and trail running offers some unique advantages:

    • Builds Aerobic Base: Runs like these are fundamental for cardiovascular fitness and efficiency, the foundation of Hyrox performance. Keeping the heart rate in a controlled zone, like aiming for under 150bpm for this run, specifically targets this.
    • Gentler on the Joints: Compared to road running, the softer, more varied surfaces of trails can be gentler on the knees and other joints, which is beneficial when managing overall training load, especially with higher running volumes.
    • Strengthens Ankles & Stabilizers: The uneven terrain of trails forces your ankles and smaller stabilizing muscles to work harder, improving proprioception and resilience against injuries – crucial for navigating Hyrox obstacles and varied race surfaces.
    • Reinforces Habit & Routine: Showing up, even when original plans change, keeps the fitness habit alive.
    • Mental Well-being & Connection to Nature: A trail run can be a fantastic stress reliever and mood booster. The fresh air and connection to nature offer mental benefits that go beyond the physical.
    • It All Adds Up: Consistent efforts, even if they aren’t always at peak intensity or maximum duration, accumulate over time to build significant endurance.

    My Experience & Reflections

    I went into this run knowing it was likely the only significant movement I’d get for the day due to work. While I was initially disappointed that my planned afternoon workout wasn’t going to happen, getting this ~80-minute trail run done felt like a solid win. It wasn’t about chasing paces, but more about sustained effort in nature and keeping my heart rate in that aerobic zone. The trails always offer a good mental reset. It’s a strong reminder that flexibility is key in training; sometimes you have to adapt to life’s demands and still find a way to get quality work in that aligns with your goals.

  • May 26 – My “Rest Day” 15km Run: The Power of Zone 2 for Hyrox

    May 26 – My “Rest Day” 15km Run: The Power of Zone 2 for Hyrox

    So, my legs have been staging a pretty vocal protest after the volume I threw at them last week. Clearly, a proper rest day was in order. And what better way for a “Seamus-style” rest day than a cheeky 15km run, right? (Yes, I know, the irony isn’t lost on me – it’s a classic move, and some of you have come to expect these kinds of shenanigans!)

    Despite the “rest day” label, today’s 15km run on Monday, May 26th, 2025, had a very specific purpose: maintain Zone 2 heart rate throughout and continue building that crucial aerobic base. This kind of session is a cornerstone of my training, especially with Hyrox Toronto on the horizon.

    The Goal: Zone 2 and Aerobic Base Building

    The primary intention for this run was to spend quality time in Zone 2. This wasn’t about speed or pushing the pace; it was about sustained, controlled effort to enhance my aerobic capacity. This type of training is fundamental, and I want to explain why it’s so beneficial, particularly for endurance events like Hyrox.

    The Power of Zone 2 Training for Hyrox (and Beyond!)

    Many athletes fall into the trap of thinking every run needs to be hard and fast. While high-intensity work has its place, the vast majority of your endurance training should actually be done at a lower intensity – this is where Zone 2 training comes in.

    What is Zone 2? It’s a conversational pace, an effort level where you can comfortably hold a conversation. For most, it corresponds to about 60-70% of your maximum heart rate.

    The 80/20 Running Principle: This popular training philosophy suggests that about 80% of your weekly running volume should be at a low intensity (like Zone 2), with only about 20% dedicated to moderate and high-intensity efforts. Why? Because this approach builds a massive aerobic foundation with less risk of injury and burnout.

    Benefits of Zone 2 Long Runs for Hyrox Training:

    • Improved Mitochondrial Density & Function: Mitochondria are the powerhouses of your cells. Zone 2 training increases their number and efficiency, meaning your body gets better at producing energy aerobically.
    • Enhanced Fat Utilization: Training in Zone 2 teaches your body to become more efficient at burning fat for fuel, sparing precious glycogen stores for higher intensity efforts during a long race like Hyrox.
    • Increased Capillary Density: More capillaries mean better blood flow and oxygen delivery to your working muscles.
    • Stronger Cardiovascular System: Your heart becomes more efficient at pumping blood.
    • Improved Lactate Threshold: While higher intensity work directly pushes your lactate threshold (the point where lactate accumulates faster than it can be cleared), a strong aerobic base built through Zone 2 work allows you to sustain efforts closer to that threshold for longer. It also helps with lactate clearance and recovery *between* high-intensity efforts (like Hyrox stations).
    • Better Recovery: Low-intensity work promotes blood flow and can aid in recovery from harder sessions.
    • Mental Toughness: Spending extended periods in Zone 2 also builds mental discipline and the ability to stay focused for long durations – invaluable for a Hyrox event.

    For Hyrox, where you’re constantly switching between running and demanding strength stations for over an hour (or much more!), having a deep aerobic well to draw from is non-negotiable. Zone 2 training builds that well.

    My “Rest Day” 15km Run Experience

    As mentioned, my legs were definitely complaining when I started out today. The goal was a steady Zone 2 effort. The first 8km went pretty smoothly, keeping my heart rate and pace where I wanted them. However, around the 9th kilometer, my watch decided to have one of its characteristic glitches (a recurring theme, it seems!), and the data feed went a bit haywire. I had to slow down considerably for a bit to try and get it working again, which explains the significant drop in pace and heart rate you’ll see for lap 9 in the data below.

    Once that was sorted (as much as it could be), I settled back into a rhythm for the remaining kilometers. The overall average pace was **6:48 min/km** for the **15.02 km**, which took **1 hour, 42 minutes, and 3 seconds**. Given the initial leg soreness and the watch drama, I was content with maintaining a predominantly Zone 2 effort and just getting the time on my feet.

    Why This Run Matters for Hyrox

    Even on a “recovery day,” a run like this serves multiple purposes for Hyrox preparation:

    • Reinforces the aerobic base necessary to sustain effort through all 8km of running in a Hyrox race.
    • Trains the body to recover efficiently between bouts of higher intensity (simulating recovery between stations).
    • Builds mental resilience for longer events.
    • Provides an opportunity to practice pacing and listen to your body.
