Ski Coach in the Winter, Bike Racer in the Summer


Dai Endurance Athlete of the Week is Mark Mirviss!!


  1. What do you do in real life?
    In the winter, I coach Masters Skiing/ski racing.
    In the summer, I ride my bike…a lot!
    I also fly small airplanes, and instruct…a bit.
  1. What are your weaknesses?

My “snarky” attitude!
Somewhat intolerant of laziness among others.

  1. Why are you training?

To become a more proficient rider/racer

  1. Do you partake in any Dai Endurance Classes/Training/Fitting?

My bikes were professionally fit to me by Julie Young. I can not stress the importance of this. It is akin, in the skiing world, to having ski boots that are not balanced (canted) to the individual.

  1. Favorite piece of technology for training?

I have started this season using a dual sided power meter. This is a sizeable investment in technology, (and sometimes a pain to keep working properly) but well worth it.

  1. If you could spend 10 days anywhere, where would it be?

Riding in the Dolomites!


  1. Do you have a pre-ride/run food you like to have?

No, not really.

  1. What is your favorite food to eat post training?

A taco (and a beer).

  1. Do you enjoy coffee/espresso or tea? What’s your preferred brand?

I did not drink coffee until about 5 years ago, and now roast my own. So, the brand would be, well, I haven’t (and won’t) market it.

10.Why do you train with Dai Endurance?

I coach ski racing, and as such, realize the benefits of having a coach. A coach is an unbiased observer of athletic performance. As well as someone trained and knowledgeable in the subject matter. Therefore, a coach is able to recommend a training program/exercises that will make the sport, (in this case bike riding) more efficient, more gratifying and more pleasurable.
