About the event

We proudly present Seattle's Earth Day Run April 17th . Come run or walk one of our many race distances and at the same time you can feel good about supporting the environment. Each finisher will receive a native sapling tree + an additional tree will be planted for each finisher we have. Over the years at our Earth Day events we have handed out thousands of trees that grow and sequester more and more carbon each year. On top of all that we will also be recycling old running shoes so don't forget to bring them so we can donate them to Africa via the More Foundation Group. Tell your friends and come out for this great event!


Day of race registration and bib pick up: 10 min before your start time

Kids Dash: In-between waves

All events: at your designated start time


Visit our potting station after the run...


At the Tree Hugger Station you can pot a tree for the parks department, take a sapling home with you as well as learn about native trees and best practices for planting.

How Green is the event?

Best in the nation. We give out a native sapling tree for each participant to plant themselves or donate to the park to be planted. For each finisher that crosses the line the Mangrove Action Project will plant a mangrove tree in their name. Mangroves are the number one carbon sequestering tree on the planet. We donate used running shoes to the More Foundation which uses the proceeds from the sales to help people in Africa grow fruit trees, gardens and more. We also have partnered with Arcadia Power so all the electricity that our event produces will be purchased through wind power. All end of race fruit is organic and we recycle and compost all waste.

Different ways to plant your tree for Earth Day:

  1. At our potting station
  2. In your yard
  3. Give it to a friend for their yard
  4. Pot the tree at the event
  5. At a park, traffic circle, sidewalk or other outdoor areas.
  6. Pot it and bring it back to our Fall Planting Party at Magnuson Park 

Our recommendation is to plant the tree in a pot and let it mature for a couple years then find a suitable place to plant it. You can always bring the tree to our Fall planting party as well, details will be emailed to participants before the event. Don't forget to read our Proper Tree Placement page when deciding where to put your tree. To view click here. 

400 meter kids dash

15 minutes before the main event we always hold a 400 meter dash for the kids.


On site planting location

If you would to plant a tree in the park stop by the location below and look for the Seattle Green Partnership sign and the planting coordinator is Thomas Kelly.

4. Benefits of Trees


 Investing in trees is one of the best investments you can make:

1. A single tree can absorb 10 pounds of air pollutants a year, and at the same time produce nearly 260
pounds of oxygen- enough to support two people.

2. Forests provide natural filtration and storage systems that process nearly two-thirds of the water supply
in the United States. Trees help filter water, help prevent soil erosion, moderate runoff during rain storms as well as increase groundwater aquifers.

3. Trees also reduce the greenhouse effect by shading our homes and office buildings. This reduces air conditioning needs up to 30%, thereby reducing the amount of fossil fuels burned to produce electricity. This combination of CO2 removal from the atmosphere, carbon storage in wood, and the cooling effect makes trees a very efficient tool in fighting the greenhouse effect.

4. Crunch the numbers: Over a 50-year lifetime, a tree generates $31,250 worth of oxygen, provides
$62,000 worth of air pollution control, recycles $37,500 worth of water, and
controls $31,250 worth of soil erosion.

   5. A U.S. Department of Energy study reports that trees reduce noise pollution by
   acting as a buffer and absorbing 50% of urban noise.

   6. Mature tree's can increase property value 5-15%.
