How to Train for HYROX: Building Your Aerobic Base, Strength, and Race-Specific Fitness | Coach’s Corner
After speaking with Ben Seymour, a former professional rugby player and ultra-endurance athlete, the coaches come together to discuss what a real HYROX prep block looks like. They break down what’s required and explore an issue many people run into when training for mixed sports: how to train properly. Your body can only do so much at one time, which is why it’s important to break up your training. Trying to build strength, power, and endurance at one time rarely works. Instead of splitting your training time equally between the race demands, they suggest assessing your capabilities, figuring out where you’re strong, and building a plan around the gaps. From there, they explain in detail how to build a 16-week structured training system. The first four weeks begin with building an aerobic base and foundational strength. During this time, you can also add threshold and interval work to raise VO2 max and teach faster recovery. The following weeks shift focus to race-specific training built around compromise running and moving under fatigue. Later in the conversation, the coaches discuss why HYROX is considered more of a running race with strength stations built in, what it means to pace yourself against your lactate threshold, and why mental strength and energy management matter as much as raw fitness on race day. In This Episode You’ll Learn: (00:01:16) Why coaches usually build a plan around one or two adaptations at a time, not all of them at once (00:03:55) Why HYROX is really a running race, with roughly eight kilometers covered across the event (00:04:19) The pyramid analogy for aerobic base, and why a wider base supports a higher ceiling later (00:05:04) What the first four-week training block of a 16-week structure should include (00:07:03) What threshold work is and how to recognize when you've crossed your own lactate threshold (00:08:06) The most common pacing mistake people make (00:08:55) What VO2 max actually measures (00:11:08) Why compromise running, training runs done under fatigue from strength work, matters more than steady-state mileage as race day nears (00:12:23) The difference between fitness and conditioning, and why "educated energy expenditure" decides who fades late in a race (00:13:01) How the SAID principle explains why practicing race-specific movements under fatigue builds real race readiness (00:15:21) A sample five-day-a-week training split for someone training for HYROX, and how it shifts across the four phases Resources: Follow Ben Seymour Instagram: @seemorebenny Website: benseymour.com.au Raise the Bar Podcast: Experience OneCoach: https://one.coach/ Visit One Playground: https://oneplayground.com.au/ Follow Raise the Bar: https://www.instagram.com/raisethebarpodcast/ Follow Ariel: https://www.instagram.com/arielcomeau_/ Follow Matt: https://www.instagram.com/mattduncancoach/
