Cycling is the longest leg of a triathlon. It is also the discipline where the biggest time gains are often possible. Whether you are training for a Sprint triathlon, a Half, or an Ironman, improving on the bike will not only help you ride faster, it will also leave you fresher for the run.

Build your endurance to get faster on the bike
Before trying to increase your speed, it is essential to build a strong endurance base. To improve your cycling in triathlon, most rides should be done at a comfortable intensity, where you can still hold a conversation. These sessions improve your ability to sustain effort for several hours and form the foundation of any triathlon training plan.
Week after week, gradually increase the duration of your long rides so your body adapts to the demands of your goal race.
Do not ride at the same pace all the time
If every ride is done at a steady moderate pace, progress quickly stalls. Just like running, cycling performance improves with an alternation of intensities.
Short intervals help develop power, while longer efforts at threshold improve your ability to hold a strong pace. By varying your bike workouts, you will improve for both short-course triathlon and long-distance racing.
Work on your cadence
Cadence is the number of pedal revolutions per minute. A smooth cadence places more of the load on your cardiovascular system while reducing muscular fatigue.
Every triathlete has a natural cadence, but learning to pedal between 80 and 95 rpm is often a good benchmark on flat terrain. The goal is not to force a specific number, but to find a pedaling rate that feels both efficient and comfortable.
Improve your cycling with hill work
Triathlon bike courses are not always flat. To get better on the bike, it is important to include elevation in your training too. Climbs naturally build strength, improve your pedal stroke, and strengthen the muscles you rely on during long rides. A few repeats on a steady hill can be just as effective as a dedicated strength session.
Follow it up with a run
One of the unique challenges of triathlon is having to run immediately after the bike. The famous “brick sessions” help you gradually prepare your legs for this demanding transition. You do not need to run for long, ten to twenty minutes is often enough to reconnect with the specific feeling of the bike-to-run transition.
Optimize your position
A good bike position helps you produce more power while improving aerodynamics and comfort. Many triathletes lose valuable minutes simply because they ride in an inefficient position. That is why it can be worthwhile to check your setup with a bike fitting, especially if you are preparing for a Half or an Ironman.
Use a structured training plan to improve
To make lasting progress, it is important to alternate endurance rides, quality sessions, and recovery periods.
RunMotion Coach triathlon training plans include bike sessions tailored to your level and your goal. Workouts progress gradually from week to week and fit alongside your swim and run sessions to create balanced triathlon preparation.
In the app, select the days when you want to train on the bike, then for each day choose whether you want to ride on a road bike, gravel bike, MTB, or indoor trainer, and what you want to work on: endurance, strength, or simply let your coach decide.
Here is an example of bike workouts to help you improve that you can find in the RunMotion Coach app (available with the premium version):
Road cycling workout to build endurance
Ride for 2 hours at low intensity
Road cycling workout to work on intensity
Ride 20 min at low intensity
5×10 min at 95% FTP with 3 min recovery between each 10 min effort
20 min at low intensity
Key takeaways to improve your triathlon cycling
Getting better on the bike is not just about riding more. The variety of your sessions, the quality of your pedaling, hill work, and an optimized position all help you become more efficient while arriving fresher for the run.
With structured, consistent training, progress often comes quickly, whatever your level.
