Marathoners warned of risks from high temperatures

The Boston Athletic Association issued another update to all entrants in Monday's 116th Boston Marathon on Sunday that outlined the risks they face and urged runners to consider their decision whether to participate carefully.

Monday's forecast calls for high heat. An advisory attached to the BAA's update sent Sunday afternoon from the race's medical directors says the race will be run in a "red zone" condition, which is considered increased risk but acceptable for high-level elite runners.
