Career
On 20 August 1950, during the Tour of Germany, Pellenaars hit an American military vehicle at high speed, and was crashed so seriously that a Belgian newspaper published his obituary. He recovered, but retired from racing and focused on coaching. This career came to an end in 1962, when national teams at the Tour were replaced by individual professional teams.
He continued coaching over the next decades, in particular the Goudsmit-Hoffploeg since 1971, but without much success.
Pellenaars was born to Petrus Pellenaars, a farmer, and Cornelia Wilhelmina van Alphen. They had no children.
