At 10,000+ feet, against the misty backdrop of a former mining town, Leadville, Colorado, 1228 cyclists line the starting line. For many, it will be the most difficult race of their lives. For some, a bragging right to say they raced alongside the best in the world. Some imagine victory. Most hope only to finish. But everyone will count.

The race that started 25 years ago as a running race to drive tourism in Leadville has now grown to a lottery cap of 1000+ competitors, many of them the world’s most elite cyclists. But the Leadville Trail 100 “Race Across the Sky” Mountain Bike Race is not just a race of man against man:  it’s man vs. man, man vs. self, man vs. elements, man vs. time. A clock set for 12 grueling hour’s slugs through 100 miles, over 14,000 vertical feet of climbing, some two miles above sea level, through extreme climate changes ranging from heat to hail, from rain to snow.  To the racers, the risks of injury, fatigue and mechanical failure pale next to the chance that they will fall behind the 12 hour cut off mark and be eliminated.

Rivalries include six-time defending champion Dave Wiens vs. international star / seven-time Tour de France winner Lance Armstrong.  Inspirational stories of human triumph include a Leadville woman rider who was critically injured by a car while training for last year’s race, another who suffers from multiple sclerosis, and 45+ rider who has raced all 15 years.

Whether they’re international stars of the sport or everyday folks with the will to finish a race whose difficulty is on par with the Ironman, the grit to push to their own physical and emotional limits strikes an elegant symmetry between racer and environment and a struggling former mining town whose very existence now relies on the tourism generated by this race.

“Walk In The Clouds” is a story in three chapters.

Chapter One (03:00 min.):
The film begins with a Voice over monologue by the Ranger (Robert Redford). Leo Kottke solo guitar music mixed over a lush background of ambient mountain forest sounds is behind the voice over. Visuals are striking still images of Glacier National Park. The Ranger describes, in his terms, what makes this park special to him. He touches on several themes very briefly, geology, climate change, wildlife and hopes it may trigger something in you, to go out and witness it for yourself, to Walk In The Clouds.

Chapter Two (06:00 min):
A distinct mood change. The Philip Glass Symphony Number Four, first movement “Heroes” begins. Visuals now are full color dramatic moving images of the park. There is no Voice Over. The visuals are showing all the things the Ranger was talking about previously. For six minutes the viewer in immersed in a wilderness dream.

Chapter Three (00:30 Min):
As the music and visuals begin to fade out the ranger comes back with a final statement about the importance of wilderness and the threat of loosing it.
