Sarah O'Donnell
Coach
Sat 9AM, Sun 9AM
Sarah was inspired by Crosswim to begin doing sprint triathlons in 2022. She has since completed one half Ironman and one full Ironman and is always looking for her next challenge.
What she loves most about Crosswim is the camaraderie of athletes trying to become 1% better every day. After all, suffering is more fun when you share it with others!
In her spare time, Sarah can be found playing beach volleyball, training for her next athletic challenge, planning her next road trip, or perfecting her zucchini bread recipe.
If she could give you any words of motivation, it would be “the sooner you get in the pool, the sooner you get in the pool.” Sometimes the hardest step is the first one.
Marc Massaro
Coach
Sat 9AM, Sun 9AM
Marc is a trail runner and gym devotee who brings energy, humor and a ‘misery loves company’ mentality to his Crosswim workouts which he has been involved in for over a decade.
A native of Chicago who grew up as a competitive and collegiate swimmer, he is a USMS Level I and II coach and certified Adult Learn-to-Swim instructor. Marc loves helping individuals reach their personal fitness goals and working with people of all ages and levels.
Marc has completed multiple ultramarathons as well as several IronMan triathlons, masters and open water swimming events and is open to pretty much any kind of athletic endeavor. Always looking for new challenges and ways to push his limits, ‘work hard, play hard’ and ‘deserve your dream’ are his personal mantras.
When he’s not coaching or participating in suffer-fest activities, he can be found working his day job at State Farm or at a brewery with his partner in crime Kelley.
Tommy Hardison
Coach
Tues 6PM, Thurs 6PM
Tommy is a Crosswim obsessive and has been participating in and coaching Crosswim for 10 years.
His passion is driving people to be more than they think they can be by challenging them (sometimes literally) to improve every day.
Tommy is a versatile athlete and his skills range from running and basketball to diving with sharks.
When he's not at Crosswim he can be found delving into his deep love of cinema or at the gym.
