BOSTON (AP) – Despite weather forecasts that raised fears of widespread hypothermia, Boston Marathon organizers were pleased that early tallies showed just the usual aches and pains.

“I think things are going very well. Better than expected,” medical coordinator Chris Troyanos said shortly after elite runners crossed the finishing line. “The anticipated concern with the temperatures and the rain and the wind, we thought we would at this point in time we’d have a higher casualty rate.”

About 30 runners were suffering from hypothermia and were being treated in the medical tent near the finish line – a higher than normal figure, according to Joan Casey, a nurse and race volunteer. One runner’s temperature was measured at 92 degrees.

“That’s low,” Casey said. “You want to warm them up.”

Some runners had their upper bodies wrapped in a special blanket that attaches to a portable heater while medical staff monitored their temperatures. Two runners were sent to the hospital after consuming too much water, Casey said, mainly as a precaution.

As determined runners limped, walked and stumbled to the line, race officials said they were surprised by the low number needing medical care. That may be partly due to warnings that organizes sent to runners to prepare for bad weather.

“I’m really kind of surprised it isn’t busier,” Troyanos said. “Sending an e-mail blast Thursday and Friday was very helpful.”

Totals of those seeking treatment were not expected until Tuesday.

Guy Morse, executive director of the Boston Athletic Association, said organizers spent unprecedented amounts of money to provide heating tents, emergency services and other facilities to runners in this year’s race.

“We were hemorrhaging money in order to provide a safe environment for the runners,” he said. “If we have one of these every 111 years, we’ll deal with it.”

Morse said he was relieved that the race worked out so well despite dire predictions in the hours leading up to the marathon.

“It looked very bad last night,” he said. “Hopkinton in particular was sinking fast, so to speak. One of the (athletes’) villages was completely under water.”
