It’s time for Challenge Henry. Recently Ivan Yates asked Henry McKean to become Green for the day, he had to take public transport and eat in-season sustainable food and wash himself only with a big bar of soap. He failed spectacularly.

So we thought we would up the anti by 90. We asked you the listener, what you want to Challenge Henry to do.

We have sack fulls of emails sent to ChallengeHenry@Newstalk.com, they include, get naked to delivering a lamb.

We are going to dive into this series and create a splash. Starting with an idea sent to us. ‘Ask Henry to dive off a 10 metre diving board into an Olympic swimming pool with an Olympic diver.’

Oliver Dingley Commonwealth Games Bronze Medalist before he switched countries to Ireland under the Granny rule.

He represented Ireland in Rio and was a finalist and will be going to Toyko for the 2020 Olympics. He is sponsored by Dublin Port and is training hard. He took time out of his schedule to train me how to dive at the National Aquatic Centre.
