In May last year Matt Toole completed the Cigna 10km event at the Air New Zealand Hawke's Bay International Marathon with a kidney operating at just 10 per cent.
This year 28-year-old Toole is back, this time with a transplanted kidney to help him on his way to what he hopes is a better finish-line experience for his mum Pat.
In 2017 he took on the event just six weeks before having transplant surgery. The 10 per cent function in his kidney meant he was a little ''worse for wear'' when he crossed the line.
"The main thing for me this time round is my mum and leaving her with a slightly better memory of this event.
"She was at the finish line last year and I must admit, it was probably a tough watch. I remember being absolutely drained and white as a ghost as I crossed the line, so I think it will be good for her to see my recovery is going really well, and I'll be coming over the line in a healthier state.
