The Importance of the Race Day Warm-Up

Race day warm ups

Race day warm-up: does it really make a difference?

My initial response to this question is yes. But, that’s the simple answer. The more complicated answer is: it depends.

Read on for eight tips on how to understand which factors matter for you, how to get more out of your warm-up, improve race results and learn sample warm-up strategies for your next triathlon.

The importance of a warm-up

The warm-up is important as both a physical and a psychological preparation. By developing a regular warm-up routine, you can decrease uncertainty and anxiety as you direct your attention to preparing your body to meet the physical demands of the competition. Your warm-up routine can be systematically designed to promote optimal functioning in the final few minutes before performance. 

Experience level and performance goals

For beginners or those with triathlon completion goals, a warm-up is not critical, but is still beneficial. Participation and enjoyment are the goals, so a warm-up is not a priority. But even a short dunk before the start will help you be better prepared for the challenges ahead. If you are more experienced or want to achieve faster times in your race, then a warm-up is critical to your success. It’s unreasonable to expect your best performance in a race if you have not properly prepared both physically and psychologically for the demands of your race, especially for a fast start. A proper warm-up is an integral part of planning and preparation.

Race distance

The shorter the race distance, the more important a warm-up is.  Faster speeds require more ‘priming’ of your engine (heart, lungs, muscles and nervous system, including your brain).  You will feel better and perform better if your body is ready for the demands of a hard, fast race.  But, for a long distance race, such as IRONMAN, a light or even no warm-up may suffice to conserve energy for the long day ahead.

Two tiered warm-up

A warm-up can consist of one or two types of activity: easy, low level effort and/or short, higher intensity efforts. The first type of warm-up to do is easy paced efforts. Since most races happen in the morning hours, it‘s important to get your body to really wake up and start moving by activating and warming your muscles and getting you heart rate up. The easy warm-up transitions your body from rest to activity. The second tier of a warm-up consists of short intervals and drills (light plyometrics). Complete a low intensity warm-up if you are new to triathlon and both tiers if you’re experienced and looking for improved performance.

Race warm-up starts the day (or two) before race day

I call the day before race day workouts: pre-race warm-up day. In the days leading up to a triathlon, most of us are resting to taper for the race. After long periods of regular activity, rest can leave our bodies feeling tired and sluggish. While the rest is important, getting back to activity before your race will leave you feeling strong and ready to race instead of feeling flat for your race. 

Athlete type

Although all bodies will benefit from a good warm-up, not all bodies need the same type and amount of warm-up. If you tend to have more fast twitch muscles and are better at speed activities, you’ll benefit from more intensity in your warm-up and may need some intensity for 1-2 days leading up to the race. If you’re more of a diesel engine (more slow twitch fibers), you’ll benefit from a low intensity aerobic warm-up with only small amounts of intensity.  This is partly a concept that is learned through trial and error.  One of my triathletes raced back to back days at USAT Nationals and did better on the second day’s race, a sprint. I learned that he needs more intensity than most leading into a race to achieve his best results. But that same strategy for other triathletes would leave them too tired to perform well on race day.

Sample day-before warm-up workouts

Perform a short swim, bike and run in any order that works for your schedule. It’s also OK to opt for only one or two of these workouts. If possible, do these on the race course. Example:

  • 15-20 minute swim. Option: 3-8 rounds of 20 strokes fast/10 strokes easy
  • 15-30 minute bike. Option:  5x1 minute fast spins or race efforts with 1 minute recovery. Followed by a 2-3 minute build to race effort or threshold
  • 15-20 minute run. Option: 5-10 minutes of light drills. 4-6x10-15 second strides, 2 minute jog/walk recovery.

Perform the short intervals within the total suggested time. By performing this type of workout the day before the race, your morning warm-up routine will be quicker, smoother, easier to perform and give you the best results.

Sample race morning warm-up

Choose one to three of these options; much depends on race requirements such as bike check in and swim course regulation. Suggested order:

  • Bike: 10-15 minutes easy. Option: 3x30 second fast spins, 1 minute easy between. 1x1-2 minute race effort, easy spin for 3-5 minutes.
  • Run: 10-15 minutes easy. Option:  5 minutes of light drills and 2-3x 10 second strides with 1-2 minute walk/jog between.
  • Swim: 5-15 minutes. Start slow and allow your body and breathing to acclimate to the open water temperature. Option: 2-5 rounds of 10 strokes fast/10 strokes easy.

Trial & error process

The science of training and coaching can only be successfully applied to the individual through the process of trial and error. Create a warm-up plan that makes the most sense for you and your goals. Try it out in smaller triathlons or single sport races, then correct and refine it over time. Once you have your routine down, it’ll be easy to implement and will give you a strong platform to perform at your best.
