A participant in a 50-year-old endurance canoeing race on 260-mile canoe race has become the first in the event's history to die in action.
Texas Water Safari president Allen Spelce says Brad Ellis died Monday afternoon at San Antonio Military Medical Center of low sodium.
Spelce tells the San Antonio Express-News says Ellis drank water without replacing the sodium he sweated out during the Saturday and Sunday event from San Marcos to the mouth of the Guadalupe River at Seadrift.
State Game Warden Dan Waddell says the 30-year-old Dripping Springs man began to feel ill before dawn Sunday after rowing about 98 miles and fell from the canoe into the river. His rowing partner pulled him from the river and he was airlifted 70 miles to San Antonio.
