BOSTON – Days of training in the rain and snow may pay off for Amy Compston in Monday’s Boston Marathon.

The forecast for the marathon calls for 100 percent chance of rain with 21 mph winds.

Compston, who will be running in her third consecutive Boston Marathon, is ready for the elements. During her training she never let the weather detour “because you never know what it’s going to be doing in Boston on race day.”

Besides being a missionary with a heart for Africa, she’s pretty good at predicting weather.

Rains are supposed to be steady early and soaking later in the day with increasing winds. Rainfall of nearly a half an inch is being predicted.

Compston, who ran her personal best time in the 2013 Boston Marathon at 3 hours and 27 minutes, isn’t worried about the elements.

“I’m thankful for another opportunity to run in Boston regardless of what it does,” she said. “We know who’s in control of the weather and everything else. I praise God for this chance to run for Him.”

Her group will be leaving the starting line around 10:50 a.m.
