Tips to Sharpen Your Bike Leg Ahead of Race Day
The bike is the longest part of race day, so investing time and energy into improving it can deliver a significant return.
In most triathlons, the bike accounts for more than half of your total race time. Arguably, that makes it the discipline most worth investing in.
Tip 1: Practice Hills
Even if your goal race is flat, there is a lot to be gained from including hills in your training.
Cycling has a significant strength component. After all, there are only two ways to produce more power on the bike: pedal at a faster cadence or push a bigger gear.
The ability to push bigger gears for longer periods comes down largely to muscular strength and endurance, both of which can be developed effectively through climbing. As an added bonus, hill workouts often provide a welcome break from the indoor trainer and some of the most scenic riding of the year.
Tip 2: Practice the Terrain
While hill training is valuable regardless of your goal race, terrain still matters. That means studying the course ahead of time and understanding the specific demands you’ll face on race day.
If your race involves long periods in the aero position, make sure your training reflects that. Incorporate extended intervals in your TT position and become comfortable producing power while staying aero. If traffic, road conditions, or safety concerns make that difficult outdoors, dedicated trainer sessions can be an excellent alternative. One of the most important principles of training is specificity: the more closely training mirrors race demands, the better prepared you’ll be on race day.
Tip 3: Learn to Ride the Terrain
Building on Tip 2, as much as FTP, average power, and normalized power dominate cycling discussions, they are not the sole determinants of a fast bike split.
At the end of the day, the goal is simple: get from point A to point B as quickly as possible. Sometimes that means producing more power. Sometimes it means riding smarter.
For example, on a fast descent, tucking into a more aerodynamic position may gain you more sp*ed than continuing to pedal. Likewise, strategically applying extra power at key moments – such as cresting a hill, accelerating out of a corner, or responding to a change in terrain – can help maintain momentum and increase overall sp*ed.
Tip 4: Run Off the Bike
We opened this article by noting that investing in your bike fitness can not only improve your bike split, but also set you up for a dramatically better run.
To fully capitalize on that advantage, however, it’s important to practice running off the bike. Triathletes commonly refer to these sessions as “brick workouts.”
Running well after cycling is a highly specific skill. The transition places unique demands on your neuromuscular system, and the sensation of running on tired legs is something that improves with practice.
The good news is that these sessions do not need to be long to be effective. Even a 10-minute run after a key bike workout can help prepare your legs for race day and familiarize you with the transition. While it is beneficial to occasionally include longer brick runs, most can be relatively short and focused simply on adapting to the feeling of running after a hard ride.
