In this engaging discussion, Lachlan Kerin, a scientific triathlon coach and PhD candidate, shares insights into effective bike training strategies for triathletes. They explore the differences in power output between road and time trial bikes and the nuances of training on hilly terrains. Listeners learn about the importance of cadence, pacing strategies, and using rollers for skill development. Lachlan also highlights the significance of bike fitting and tire width on performance, making this a must-listen for cycling enthusiasts looking to enhance their training.
Time trial bikes typically result in a 10% lower power output than road bikes due to different muscle engagement and positioning.
Incorporating both uphill and flat interval training invites unique benefits, enhancing cardiovascular adaptations crucial for triathlon performance.
Athletes should calibrate their power meters properly to ensure accurate data, which significantly impacts training effectiveness and race-day performance.

Power Differences Between Road and TT Bikes
It's normal for triathletes to experience a lower power output on a time trial (TT) bike compared to a road bike, with a difference of about 10% being typical. This discrepancy can arise from changes in muscle recruitment patterns and the hip angle, as the TT position tends to engage different muscle groups. After a bike fit, most athletes can expect to close this gap within two to three months with dedicated training on the TT bike. The goal should be to ultimately aim for less than 5% difference or reaching approximately 15 watts lower than the road bike's output.
Interval Training: Uphill vs. Flat
Training high-intensity intervals on inclines can feel easier for some athletes compared to flat terrain, with both approaches offering unique benefits. The central cardiovascular adaptations may not vary significantly whether intervals are performed uphill or on flat ground; the key lies in the workout's goal. For triathletes, maintaining good power output at high speeds is crucial, and flat workouts can aid significantly in this regard. Therefore, strategically incorporating both types of terrain during training may yield the best results, especially as races approach.
The Role of Easy Riding in Training
With the rise of polarized training, many athletes wonder if their easy rides should be performed at the lower end of Zone 2 or the higher end. While it is possible to push too hard on recovery rides, the top end of Zone 2 can be beneficial for athletes with different thresholds. For individuals on the higher end of the FTP scale, riding towards the top of Zone 2 can be productive, whereas lower FTP athletes might need to stay closer to Zone 1 to maintain effectiveness. Balancing intensity while ensuring sufficient recovery is essential for optimal training adaptation.
Calibrating Power Meters
Calibrating a power meter is crucial for ensuring accurate data during training and races, although there is some confusion regarding calibration versus zero offset. Athletes can typically calibrate their power meters using their computer or watch, but it is vital to understand the specifications for the specific device being used. While calibration is generally sufficient, a factory calibration provides a more precise setting. Consistent maintenance and proper setup can prevent inaccuracies during both indoor and outdoor riding, enhancing race-day performance.
Handling Hilly Terrain on Endurance Rides
For athletes training in hilly terrains, the key is to adapt training techniques and expectations rather than seeking entirely flat routes. It can be beneficial to ride over hills during easy endurance sessions, as long as heart rate remains in the endurance zone, even if power output appears temporarily elevated. Efficient gear management, pacing, and avoiding excessive effort up the hills will help maintain overall workout quality. Engaging with the terrain can improve bike handling skills and contribute positively to race preparedness.
