It has been called the "most grueling championship to win in all of Sport," the Tour de France turns 100 this year. As the race is at its halfway mark, we invited a local racer into the studio today to bring us up to speed.

Jesse Vernon of Bozeman's own G.A.S. / INTRINSIK Architecture Cycling Team explained why Chris Froome, riding for SKY ProCycling, with a 3:30 lead is nearly insured the win. We'll check back with Jesse when the racers near the finale in Paris.
