Brick Workout Generator
A structured bike + run session for your level, race distance and goal.
A long steady ride with an even run straight after β the base adaptation for your legs.
- Run the first 3β5 minutes deliberately slower than goal pace: let blood flow redistribute.
- Drink on a schedule on the bike: running off the bike dehydrated is the most common mistake.
- Shorten your stride and don't reach with the heel: wooden legs invite shin overload.
Why brick workouts matter
A brick chains the bike and the run with no break between them. The first kilometers off the bike feel alien: blood is shunted to cycling muscles, cadence is scrambled, pace perception is gone. The only way to teach your body to switch quickly is to train exactly that transition. One brick per week in the 8β10 weeks before a race visibly shrinks the jelly-legs effect.
The three workout variants
The classic brick builds base adaptation: a long zone 2β3 ride and a steady run after. Repeats (2β4 Γ bike + run) pack more switches into one session and sharpen transitions β a favorite for short-course racing. The race simulation is a dress rehearsal at race intensity with full equipment and nutrition: schedule it 2β3 weeks before the start.
Frequently asked questions
How often should I do bricks?
Once a week is enough. More only makes sense in the final weeks before short-course races, where the transition decides more.
Why do my legs feel like jelly off the bike?
An hour-plus of pedaling shifts blood flow and muscle firing patterns: your quads are drained while tendons and feet have forgotten impact. Adaptation arrives after 4β6 consistent bricks.
Should I run after every long ride?
A useful habit β 10β15 minutes of easy running after the long ride: cheap in load, but consistent transition practice. A full run volume isn't needed that day.
