KUSA - Hundreds of students from dozens of schools throughout Colorado participated in National Bike to School Day on Wednesday.

In fact, more than 70 Colorado schools officially registered for the event, which is part of the campaign for safe routes to school year-round. Of course, it also encourages biking as a healthy way for children and families to commute to school and work.

Now in its second year, National Bike to School Day is modeled after and builds on the popularity of the highly successful International Walk to School Day, which was founded in 1997 as a way to bring community leaders and children together to build awareness of the importance of making our communities more walkable. Likewise, the event creates additional energy during National Bike Month - the month of May.

Since the start of Loveland's Safe Routes to School program - a partnership among LiveWell Loveland, the City of Loveland, and Thompson School District - the percentage of students walking or biking to school has increased from 24 percent to 31.7 percent in just over three years.
