The Pros & Cons of Spin Class for Triathletes

Spinning class at the gym

Loud music blaring, an instructor yelling through a headset, and sweat flying everywhere. Ah Spin Class! Spin class is essentially riding a bike, but not actually going anywhere. Spin class as an effective tool in your triathlon training plan. As with all training activity, there are some pro and cons. Below, I will discuss the advantages and concerns of spin class when used in an effective training plan.

Let’s start with the positives:

  • Save Time – Just jump in a class and go. No need to get on a bunch of gear to ride outside or drive to a safe area to ride.
  • No Cars – I have personally never heard of anyone being hit by a car on a spin bike.
  • Constant Effort – There aren’t any stop lights, cars, dogs, or anything else to make you stop. This is the biggest “bang for your buck” with spin. If you are on the bike for 45 minutes, you get 45 minutes of work. This is especially effective for interval work. You can maintian your effort for your interval without uninterrupted.
  • Weather, What Weather – Unless the AC breaks, there’s no need to worry about conditions. No hot, cold, rain, sleet. This also means you can’t use the weather as an excuse not to train.
  • Motivation – The energy from a room full of others working hard can give you the motivation to push. A good instructor will also keep the energy level high.
  • Pre-planned Workout – No need to plan or think, just show up and do the instructor’s workout. The energy spent planning a workout is sometimes harder than just doing it.

Here are some areas where spin classes lack effectiveness for triathlon training:

  • Too much intensity – Most spin classes are designed to get a good sweat going, and make the clients feel like they have put in a hard effort. This is great if your goal for that workout was high intensity, if be mindful of your intensity. A good training plan will have a mix of high and lower intensity work. Too much high intensity work leads to injury and burnout. You can still do class on an easier planned day, just dial back the resistance and intensity.
  • Bike Handling – All of these spin classes are going to give you some new found speed. Before your race be sure to work on some bike handling skills. Bike handling skills include turning, leaning, stopping, climbing, and descending. The only way to gain these skills is to go on the road and ride at your race speed. The more comfortable you are with these skills the faster you can go.
  • Speed Perception – You can put massive power to the spin bike pedals, but you don’t move. It’s important to get out on the road, and know what speed you produce for your effort. In a race proper pacing is balancing the effort vs speed. Know what effort produces what speed, sop you can properly pace during your race.

Over all spin classes are great for bike and overall fitness. I personally attend at least one class a week. I go to class with my wife, as it is a workout we can do together, and both get benefit. They are not a complete substitute for time on the road. Be sure to do some miles on the road, so on race day you are comfortable on the bike.

Do you use spin classes in your training?

  1. I do, but I also ride outdoors a lot and will be getting a trainer for home. You have to be careful with your form on a spin bike, which is why I rarely move my hands from where the brake hoods would be, or where I place them while on the aero bars.


  2. I enjoy supplementing my training with spin classes. Sometimes I incorporate a brick workout into it and jump on the treadmill right after the spinning class. It’s super fun. I call it my interval brick workout and work on speed and hills on the treadmill as opposed to my endurance brick workout with a long endurance ride followed by a tempo run.

    I don’t kill myself on the spin so my legs aren’t too fatigued for the treadmill and, for me, it works great.
