About the event

We proudly present Seattle's Earth Day Run April 18th at 10am! Come run or walk one of our many race distances and at the same time you can feel good about supporting the environment. This event takes action both locally and globally. Each finisher will receive a native sapling tree + an additional tree will be planted for you in our nations forests. 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 recycle running shoes you don't want anymore so don't forget to bring them so we can donate them to Africa. Tell your friends and come out for this great event!

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.
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. Don't forget to read our Proper Tree Placement page when deciding where to put your tree. To view click here. 
Our in the park planting session this year will be held in the Fall. We will have a potting station at the event so you can pot the tree and the park will store it in there nursery until the fall. We will contact you about the Fall planting opportunity if you would like to come back and plant the tree in the park.

 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%.
