SEA TO SUMMIT
Water moves through an unending cycle. The sun heats our oceans and seas, and water vapor takes to the air forming clouds, eventually meeting mountains and turning back into snow and rain. Water trickles down the mountains, forming streams, flowing into rivers and returning to the oceans and seas. As it runs, it brings with it nutrients, fertilizing the forests, fields and countryside in its path.
"SEA TO SUMMIT" is an environmental event that has participants travel through the sea by kayak, the countryside by bicycle, and hike up the mountain. This event encourages participants to reflect on the importance of the natural world and nature's many cycles.

Nature's cycle and SEA TO SUMMIT
SEA TO SUMMIT started in 2009 in cooperation with local governments. The goal of starting SEA TO SUMMIT was twofold; to have participants reflect on the importance of nature while enjoying the outdoors and to help revitalize local areas through outdoor activities.
SEA TO SUMMIT is held over two days. On the first day an "Environmental Symposium" is held with guest speakers to lecturing on environmental issues. The main event is held on the second day comprised of three stages; water, countryside and mountain. The goal is not only for participants to have fun during a race, but rather to be surrounded by nature and reflect on your relationship with and the importance of the natural world. To reduce the environmental impact the event leaves, participants are limited to 300 participants. In addition, a portion of everyone's entry fee is donated to the local government, which is put towards protecting the local environment.
