It's time for another Challenge Henry. We received an email sent to ChallengeHenry@Newstalk.com from the Dublin Roller Derby team asking Henry to try this unique contact sport on roller skates. So Henry put on his roller skates, velcro pads and helmet and took to the track in Inchicore Dublin to find out about this new growing sport.
Henry says it's like a rugby scrum and a scrum half on roller skates but with no ball.
If you have a challenge for Henry email ChallengeHenry@Newstalk.com there is a video on the Newstalk social channels of Henry trying roller derby which is worth checking out.
