Prosser also had the aid of the Central New York Triathlon Club, a local organization that provides resources for racers. Many club members joined Prosser in Lake Placid for the Ironman, and the group trained together weekly.
"In the winter, every weekend we'd do an indoor biking session here [at Multisport]," Prosser said. "Each person would bring in their bike and an indoor trainer to hold it in place and we'd just spend hours -- up to four hours some days -- just riding. We had a great camaraderie with that group."
The training did have its costs. Time spent running or biking was time not spent with his wife and kids.
"It is a whole family commitment," Prosser said. "There's a lot of early morning training, a lot of weekends. One of the hardest things was balancing work, 15 hours of training a week and spending time with my family."
All of that hard training paid off; on race day July 22, Prosser met his goal of completing the whole race in less than 14 hours. He crossed the finish line with a time of 13:29.
"And during each of the segments, I met or exceeded what I wanted to do," Prosser said. "I felt good all day. I was able to run the whole marathon. Most people can do well on the swim and the bike, but by the time they get to the run they're out of steam."
Prosser said the race was just an extension of his training.
"When you go into one of these things, race day should be no different from your training sessions," he said. "It's a lot of trial and error to figure out what you need. It basically came down to knowing how much water, salt and sugar my body needed to keep going, and I learned it during training."
