Poling, the pastor of Hagerstown Church of the Brethren, is using his run to collect pledges for his church's Good Samaritan Fund, which gives money to people in the neighborhood having trouble paying for utilities, rent, food, medicine or other necessities.
Poling said the fund has distributed about $11,000 to needy people in the past year or so.
He figured he'll raise somewhere between several hundred and a few thousand dollars this year to help replenish the fund. Through his JFK running, he estimated he's raised about $25,000 for church-related causes over the years.
Poling, 61, said he likes the feeling of running to better someone else's life. Even if lactic acid sets in and muscles are weary -- "when you get good and tired," he said -- he thinks, "I better do my part."
By race day, Poling will have run about 1,400 to 1,500 miles in a year. He's been covering about 30 miles a week, including a long run of about 10 miles.
He said he thinks a 30- or 35-mile run is a "critical" part of a JFK competitor's training, but the best he's managed this year is one 26-miler and one 18-miler.
"That's all I have time for," he said.
Poling -- whose best JFK 50 Mile time was 8 hours, 55 minutes, 1 second in 1994 -- said he has several area training routes, including the bicycle path through Hagerstown.
His running partner, Tim Bussard, volunteers during the race. Tim and his wife, Lisa, help at the Taylors Landing aid station, at mile 38.
"They always have soup," Poling said.
Poling said he likes the kinship that develops on the course. He'll call out encouraging words to other runners as they pass him or he passes them.
Sometimes, he runs with strangers long enough to hear their uplifting stories, such as the man from Kansas who once was overweight, but worked himself into shape for a 50-mile race.
"You really feel connected to people," he said.
Poling has promised his congregation a written recap in December about this year's race.
But many will hear from him sooner.
"... I have to preach the next day," he said. "Two services."
