Step 2: Choose Your Mileage Goal

Once you’ve decided to participate, you need to determine how you’ll get active – walk, run, bike, hike, swim, row or another way — and select your mileage goal.

Choose your mileage goal:

  • 31 miles
  • 62 miles
  • 100 miles
  • Create your own challenge


Between May 1 and May 31, you’ll record how far you travel, and ask friends and family to support you along the way.

Step 3: Raise Funds

Your fundraising efforts are critical to the breakthroughs that happen every day at Children’s Hospital of Philadelphia. Through the 31-Day Challenge, you can support our Daisy Days featured beneficiary, the Children’s Fund, or any specific area of the hospital you’d like. The Children’s Fund allows CHOP to seize new opportunities and meet unexpected needs as they arise. Learn more about why you should participate!

After registering, you will be immediately set up with a customizable online fundraising page that you can share with your family, friends or companies that may be interested in supporting you.

Remember, you can continue fundraising until June 7, 2020!

Step 4: Get Going!

On May 1, your challenge begins! Make sure you log your completed miles at least once a week on your fundraising page. Your supporters (and potential supporters) want to know how much you’ve accomplished!

We encourage you to share your progress from mobile apps such as Strava, Runtastic, MapMyRun, Nike+ Run Club or GoogleFit, and use the hashtag #31Days4CHOP.

You can also earn cool CHOP gear along the way! Checkout the fundraising incentives for this year’s 31-Day Challenge.
