Step 2: Choose Your Mileage Goal

Once you’ve decided to participate, you need to determine your mileage goal – how many miles you want to commit to walking, running or jogging during the 31 days of May.

Choose your mileage goal:

  • Single-Daisy: 31 miles
  • Double-Daisy: 62 miles
  • Ultra-Daisy: 100 miles

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. Funds you raise through the 31-Day Challenge go directly to research and care to benefit young patients at CHOP.

You can create your online fundraising page immediately after registering for the event. Personalize your page, share your story about why you are participating, and send emails to friends and family for support. An online fundraising page makes it easier for you to ask for donations — and easier for others to donate. Learn more about ways to donate.

NOTE: Team captains should create a team fundraising page that team members can link to. For incentive purposes, donations to the team page will be credited equally among team members.

This year’s 31-Day Challenge will support sickle cell research and care at Children’s Hospital of Philadelphia. You can also designate your fundraising dollars to support pediatric research, patient care, or a specific area of the hospital. Learn more about why to participate.

Remember, your last day to qualify for incentives is June 8, 2018.

Step 4: Walk, Run, Jog …

On May 1, grab your sneakers and start moving! You can walk, run or jog — using any combination of days and miles — just 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 running apps such as MapMyFitness, Nike+, Runkeeper or Strava, and use the hashtag #31Days4CHOP.
