High performance, high-compression engines need airflow to cool properly. Running at a near walking pace for long stretches as the pedal bikes struggle up those hills simply doesn't allow much airflow to the bike's radiator.
Add in a radiator that has been collecting crud for a while and thus has reduced cooling efficiency, and the chances of hitting a critical point increase significantly. Plus I figure he was watching the bike riders much more intently than his own gauges.
Still, it sucks, especially when it happens to you . . .

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...
