The race series dates back to 1983.
Over 1,000 serious runners will be filling up the streets and trails of Leadville, Colorado this Saturday. They will be there to take part in the Leadville Trail Marathon and Heavy Half Marathon, which kicks off a long series of races in the town.
The Leadville Trail Marathon is one of the most grueling trail races in the world. The course takes runners across drastic altitudes changes, including a summit 13,185 feet high. The course records are 3:32:30 in the men’s race and 3:58:08 in the women’s race.
One participant in this year’s event is Bob Alexander who, two years ago, had open-heart surgery to repair a heart valve defect that was causing him to leak backward 40 percent of his blood. Alexander’s condition had been undetected his entire life.
Since his surgery, Alexander has completed five 100-mile ultras.
The Leadville Race Series started in 1983 when 45 runners took part in the Leadville Trail 100. The series now consists of six running events and three mountain biking races spread across three months.
