As far as I know he hasn’t been part of RTE staff since about 2015 or so but he tends to pop up occasionally on the national broadcaster for major athletics competitions on a freelance basis. He was definitely commentating as part of the RTE team for the 2016 Olympics despite having left by then.
For Tokyo I think he was doing the world feed as was Ryle Nugent rather than being part of the RTE team.
Rhys McLeneghan has just won a World Championship Gold on the pommel horse on RTE2. He seemed to have gone off the boil completely since the Olympics. Fair play to him
Some months ago I had half a notion of attending this as a bucket list type of thing, it’s in Liverpool which is as close as a major competition will ever get to these shores.
