Here is what I clipped from AP wire services:

FRENCH CYCLIST ERIC BARONE WAS INJURED SUNDAY WHILE RIDING DOWN NICARAGUA'S
CERRO NEGRO VOLCANO.
HE WAS HOPING TO BREAK HIS OWN SPEED RECORD.
SECONDS INTO HIS DESCENT, BARONE'S BICYCLE SNAPPED IN TWO, THROWING THE CYCLIST
DOWN THE VOLCANO.
MEMBERS OF BARONE'S TEAM SAY THE CYCLIST WILL BE HELD FOR OBSERVATION IN A
NICARAGUAN HOSPITAL FOR AT LEAST
FIVE DAYS.
NO IMMEDIATE REPORTS ON HOW BADLY THE CYCLIST WAS INJURED.

Another report (video) shows his bike in 2 pieces and Barone up walking, although gingerly.
