30x30 Challenge

Penn's Month-Long Outdoors Program

The 30x30 Challenge is an effort to encourage the Penn community to get outside, learn about local ecology, and appreciate the beauty of nature. Join Penn's 30x30 Challenge and challenge yourself to spend at least 30 minutes outdoors in nature each day for all 30 days of April. The Challenge runs from April 1 - 30.

Did you know that Americans spend approximately 90% of their time indoors, according to the EPA? Over the last decade, researchers have been documenting what many of us know intuitively - that nature is good for our health and well-being. Regularly immersing yourself in a natural setting like a park, forest, or field- can reduce stress while boosting immunity, energy levels, and creativity.


Registration for the 2022 30x30 Challenge is now closed. Check back in the spring of 2023 for more information.

Where can I find nearby nature?

Nature isn’t a destination—it’s literally in your backyard. Green space is as close as your neighborhood park or garden. Community gardens, trails, parks, and open, natural areas are often a short diversion from your daily route. Birds, bees and other critters are always nearby. You just have to take time to watch and listen. Use our Nature Rx map to find locations both on and around Penn's campus where you can benefit from spending time in nature!

What counts as “time in nature”?

Good question! It’s simple: time in nature is about getting outside and taking time to notice and connect with the non-human life around you.

Time in nature is not always the same as being outside — most busy city thoroughfares aren’t very green or calming. But the good news for urban dwellers is that even small green spaces are beneficial if you relax and pay attention to nature when you’re there. Visit our Nature Rx webpage to learn more!

Can you give me some ideas for spending 30 minutes in nature during the workday?

  • Eat your lunch outside
  • Explore a neighborhood park
  • Go for a run outside

I missed a day – can I still participate in the Challenge?

Of course! The Challenge isn’t about being perfect. We want to encourage the Penn community to get outside and enjoy nature more often. Little by little, you can cultivate the nature habit.

How can I earn Be In the Know Bonus Action points for participating?
