Using ENGO to Unlock Brick Workouts


How ENGO Unlocks Brick Workouts
The bike-run brick workout has been a triathlete’s training staple since the advent of the sport. Its purpose is to improve overall performance by familiarizing you with the unnatural sensations (and initial discomfort) of running off the bike.
The classic brick combines back-to-back efforts of cycling and running.
Benefits of Bricks
A brick workout replicates the second transition (T2) of a triathlon. Practicing your shift from cycling to running will reduce your time spent in T2, giving you some “free speed.”
Less obvious, triathlon is a strength-based sport. Bricks build durability, teaching us how to adapt our stride and pace, and helping us maintain good technique while fatigued.
Brick workouts also build mental toughness. No matter who you are, running immediately after a long bike ride is uncomfortable! Your legs feel like…well… like bricks as blood flow is redistributed and muscles unused during the bike are reawakened and activated for the run.
A Better Brick
If new to triathlon, your weekly brick might simply be a 1-hour ride followed by a 15-minute run. However, if you have a few races under your belt and are intent on getting faster, then you’ll benefit from brick workouts with more complexity.
In the following example of a more advanced brick workout, you’ll notice a run-bike-run format that includes numerous efforts at IRONMAN 70.3 intensities:
|
Segment |
Distance/Duration |
Detail |
|
Run |
5 km |
Goal race pace (hi Z2) |
|
Bike |
2 hours |
15 min: lo Z2 Repeat 2x: 15 min: lo Z2 15 min: hi Z2 15 min: lo Z3 15 min: Z2 |
|
Run |
5 km |
Goal race pace (hi Z2/lo Z3) |
The run segments should not feel “all out”; the goal is to mimic your projected race pace and build efficiency when fatigued.
The bike segment is ideally suited for triathletes who use a power meter, but you can also manage the intensity blocks according to heartrate or RPE.
Key to Brick Success
The secret to getting the most benefit from variable speed workouts like this is the obsessive management of pace.
You’ll obtain optimal training adaptations by feathering your intensities as prescribed. Going harder than instructed will affect different energy systems, which is not the purpose of this session. In this workout, we want to familiarize you with brief segments of race-like efforts that you can call upon during your event.
The ENGO Advantage
Before the advent of ENGO’s near-eye display technology, managing workouts like this was a nightmare.
Now, when wearing ENGO Eyewear, your power numbers and interval splits are projected into your field of view for real-time awareness of performance, at a glance, allowing you to focus on your effort, your aero position, and what’s ahead of you on the road.
For time-crunched triathletes intent on wringing the most value from their limited training time, ENGO Eyewear is a gamechanger.

How is engo3 different from Meta Oakley Vanguard?
engo3 is a pure performance display built for serious runners and cyclists: a lightweight AR heads-up display (38.5g) that projects your stats (pace, heart rate, cadence, and more) right in your line of sight, with 20+ hours of battery life and no camera, music, or notifications to distract you.
The Oakley Meta Vanguard is a general-purpose smart glasses product with a built-in camera and Meta AI, giving you sport stats through voice commands or audio rather than a visual display, with about 9 hours of battery life.

Yes!
Does engo3 have a camera?
No, engo3 doesn't have a camera. It's built purely as a data display: no camera, no music, no notifications, just your real-time stats (pace, heart rate, cadence, etc.) projected in your field of view. That's a deliberate choice to keep it light (38.5g) and focused on performance rather than content capture.
What is the weight of engo3?
38.5 gr
