Monday’s Brick: Miguel and Jenna’s 70.3 Simulation Brick

Race-Pace for an Ironman 70.3 is typically Level III, an intensity that you can sustain for a few hours. Having quality race simulation sessions can boost your fitness, and prepare you mentally for a great race. This is a perfect session for triathletes competing in Ironman and Ironman 70.3 distance events.

Each week I will post Monday’s Brick session that you can do to enhance your triathlon performance. For a full understanding of my Level’s intensity system, please read my previous articles about intensity for cycling and running.

The inspiration for this workout comes from a YouTube video and the Strava of Miguel Mattox and Jenna Haufler titled MOCK TRIATHLON DAY – half-Ironman effort bike-run brick workout. See below for their Strava workouts. They are up and coming pro triathletes trying to make it, give them some love on YouTube (like and follow them) and the same on Instagram (linked above). They have some really good content on YouTube and Instagram.

Start this brick with a two and a half hour ride. The first 30-minutes is your Warm Up (WU) at Level II. Then increase your effort to Level III for the next two hours.

Transition onto the run.

Start the run at Level III for twenty-minutes.

Then move into a Cool Down (CD) for a further 25 minutes at Level II.

    Anna Cochrane
    “I was recommended to Ray by a friend. He gave me a plan which was essential for me to complete my first 70.3 triathlon in Taupo. My cycling has improved significantly due to his Velocity training sessions! He shared so many handy tips and tricks, and I appreciated all his encouragement to help me believe I could do it! Thanks Ray!” 🙌

    Jason Ford
    “So far for me, I’ve completed a half Ironman event, which I never thought I’d be able to do. I’ve got to the point where I’m comfortable swimming longer distances, lost about 10 kilograms. It’s good to have a personalized program that isn’t a one-size-fits-all, like you find on the internet… You’ve got an approachable coach who will take on your feedback and work with you around life. Just having that adaptability and personalization has really been key for me.” 💪
