  • My background

    For the last 6 years, I have gone from being new to the sport of triathlon to placing top 10 at one national event and top 45 at another. This improvement immediately engaged me to see if and how I could bring this success to others around me.


    Past clients include 4 speed skating national team members, triathletes, runners, cyclists, and other endurance athletes. I have also performed DXA scans to measure bone structures of professional basketball players and collegiate runners.

    • Coached 50+ adults and juniors
    • Started a pro bono youth and junior team (triathlon, mountain bike, and cross country running) for ~15 low income Latino youth on Milwaukee's south side
    • Assistant track and cross country coach for Marquette University High School
    • Physiological assessment: 100's of tests including VO2 max, strength and power testing, metabolic testing, and running gait and pressure 

    I specialize in individual coaching, helping to find a balance between work/life and sport. Using typical (heart rate, power, RPE) and new (running power meters) data to make training plans, I've helped many athletes--from new to the sport, to those trying to make Team USA.


    I'd love to help you reach your goals!

  • Success Stories

    A selection of comments from past clients:

    Dennis F.

    Main race: Elkhart Lake Xterra (off-road) Triathlon

    Goal: Improve on 2013's race time of 1:18:29

    Result: 1:03:53, Age group 1st place!


    I worked with Mark for about a year (2015-2016). During that time, Mark and I worked together in a number of different ways, allowing me to work toward a number of different goals. Whether meeting in person, speaking on the phone or emailing/texting, Mark was always available when I needed him, was providing targeted, timely training plans, and would quickly address any questions or concerns. Throughout our time together, my goals changed a few times - from general fitness and weight loss, to triathlon and cyclocross competition readiness to 5k speed work to help me achieve a new personal record. Mark is a solid technical coach. He was able to provide actionable feedback that led to immediate improvements in my technique. Mark helped me to develop race plans, and provided race day support to help with logistics and nerves, and helped me to focus on performing my best on race day.

    To summarize, Mark is a friendly, helpful and competent coach and trainer. I would highly recommend him to any athlete, at any level, who needs a bit of help achieving their fitness or competition goals. If I hadn't moved out of the country, I definitely would have continued to work with him myself.


    Coaching highlights: Assessing his swim stroke, which made him a smoother and faster racer. He dropped 2 minutes off of his swim, 9 mins 44s off his bike, and 2 mins 20s off his run split. A fantastic PR for Dennis!

    Ruth L.

    Goal race: Ironman Wisconsin 2014


    Goal at initial meeting: 13 hours

    Finish time: 11:53:59


    Ruth inspired me to be a top notch coach. As her hat says, she would "run happy" and more than that, she lived happy. Her awesome IM time of sub 12 hours for her first event was a great success under Coach C.
