"I did not see the sign warning me I had 10 minutes left," he said. "Otherwise I would have gone faster, I would have posted a better time. I'm now waiting for a rival."
Marchand has set multiple cycling records in the over-100s category, including traveling 16 miles in an hour at the age of 2012, and a new over-105s category to accommodate his new achievement.
"Setting goals for himself is part of his personality," his coach Gerard Mistler said. "If he tells me he wants to improve his record, I'll be game. Robert is a great example for all of us."
Marchand became a vegetarian a month before the record breaking attempt and doctors encouraged him to take up meat again before attempting the record.
"He is very small but his heart is very big," Professor Veronique Billat told CNN. "His V02 max oxygen consumption is the same as a man of half his age who doesn't do any sports."
Marchand begins each day with 10 minutes of calisthenics and indoor cycling and cycles outdoors with friends four times a week.
"I'm not here to break any record. I'm doing it to prove that at 105 years old you can still ride a bike," he said before the record attempt.
