Challenge yourself this March with Tri Inside the Y at the Manitowoc–Two Rivers YMCA! This month-long indoor fitness challenge lets you choose a Half Ironman or Full Ironman distance and work toward your goal at your own pace.

Whether you're looking to build endurance, stay motivated, or try something new, Tri Inside the Y is a great way to challenge yourself and celebrate your progress.
Registration is open now for YMCA members only! The cost is $25 per participant and includes a T-shirt.
Pick Your Challenge
Choose the distance that best fits your fitness level and personal goals.
Half Ironman Distance
- Swim: 1.2 miles
- Bike: 56 miles
- Run/Walk: 13.1 miles
Full Ironman Distance
- Swim: 2.4 miles
- Bike: 112 miles
- Run/Walk: 26.2 miles
All distances are cumulative monthly totals. You have the entire month of March to complete your selected challenge, so there's no need to finish everything in one day.
Make It Your Challenge: Resistance-Training Option
Prefer strength training? Customize your Tri Inside the Y experience by substituting resistance training for one of the three traditional triathlon activities.
Resistance-Training Requirements:
- Half Ironman: Complete 10 hours of resistance training.
- Full Ironman: Complete 20 hours of resistance training.
Resistance training may replace one of the following activities:
- Swimming
- Biking
- Running/Walking
Important Challenge Rules:
- Only one activity substitution is allowed per participant.
- Resistance training replaces the entire selected activity for the month.
- Participants must complete the other two activities at their selected Half Ironman or Full Ironman distances.
- Record resistance-training hours on your weekly tracking sheets and the remaining two activities in miles.
For example, a participant choosing the Half Ironman distance could complete 10 hours of resistance training instead of swimming, while still biking 56 miles and running or walking 13.1 miles throughout March.
Achieve Your Goals: Track Your Progress
Stay motivated and watch your progress add up throughout the month!
Paper tracking sheets will be available upon registration to help you record your daily activities and monitor your progress toward your monthly goal.
Weekly Tracking Periods:
- Week 1: March 1–7
- Week 2: March 8–14
- Week 3: March 15–21
- Week 4: March 22–31
Record your daily swimming, biking, and running or walking miles, or resistance-training hours if you've selected that substitution.
All challenge distances and resistance-training hours are monthly totals. Complete your activities at your own pace and use your weekly tracking sheets to stay on track.
