Summer is here and now is a great time to get outdoors and enjoy beautiful Colorado. Running or walking is a great outdoor activity the entire family can participate in. The 4th Annual Ent 5K Fitness Challenge is drawing near and what better way to challenge you and your family than to get out and participate!

The Ent 5K Fitness Challenge is part of a lineup of American Discovery Trail Labor Day (September 1) events including a marathon, half marathon, 5K and children's fun race. Conducted on the beautiful Pikes Peak Greenway and the New Santa Fe Regional Trail, the marathon starts in Palmer Lake, runs south through the Air Force Academy on the New Santa Fe Regional Trail and finishes at America the Beautiful Park. The other events start and finish in downtown Colorado Springs' America the Beautiful Park.

Over 1,000 runners and walkers participated in the 2007 marathon, half marathon, 5K and kid's fun run. This year even more are expected. Now is a great time to get out and get moving and the Ent 5K Fitness Challenge is an excellent way to stay active while enjoying beautiful Colorado.

Proceeds from participants (runners and walkers) in the 5K will support children's fitness programs in the Pikes Peak region. Over $5,000 was raised through this event last year!

Entry fees for the Ent 5K Fitness Challenge are $20 if you register online at www.adtmarathon.com, or $25 for mail-in, walk-in (at the Colorado Running Company), or day-of-the-race registrations. Prices vary for the marathon and half marathon.
