Now he's moving from the ice to the streets of New York as he gets set to run the New York City marathon for the first time.
The winningest goalie in New York Rangers history was forced to retire from the NHL due to a series of concussions. At 40, he is not nearly ready to rest his body. He's still too young for that.
"I've enjoyed working out and getting ready for sports," Richter said Wednesday. "One day you're done playing and it's a shock not just to your emotions because you've lost this thing but also to your body.
"When you stop, assuming you're at mid-life as a man, you kind of go, 'Oh my gosh.' You lose your fitness and at that age you're losing muscle mass and everything else, it's not a bad thing to try to start some sort of workout program."
Once he got over his concussion symptoms and was able to increase his stamina, Richter found a nice way to keep in tip-top shape. He teamed with financial services group ING - the title sponsor of the New York City marathon - and set out to finish the famous race that will be held Nov. 4.
He also is working to encourage more boys and girls in New York to fight childhood obesity and get active as part of the national ING Run for Something Better program. Richter spent Wednesday on a media tour announcing his plans, also making a stop on Randalls Island for a kids track meet.
New York will be his first marathon, but Richter already completed an ironman triathlon.
"Since retiring from hockey I have become an avid endurance athlete recognizing the long-term fitness benefits of running, cycling and swimming," Richter said. "By setting a goal to complete the ING New York City Marathon, I hope to inspire thousands of children in the city to set their own personal fitness goals and work toward them properly through the ING Run for Something Better program."
That program, operated in partnership between ING and the New York Road Runners Foundation, encourages a healthy and active lifestyle in the fight against childhood obesity.
Richter will wear a pair of orange shoelaces, given to kids' fitness supporters who make a charitable contribution to the ING program at www.orangelaces.com.
