Kieran Read reveals his stunning body transformation, completes 85km trek

Since retiring, the double World Cup-winner has become obsessed with long distance treks and has shifted a lot of that weight to give him the endurance he needs.

He wrote: "Had the pleasure and pain of running 85km in the @oldghostultra yesterday. What an incredible event to be a part of. The whole Old Ghost team and volunteers were amazing, from keeping the vibe and the morale strong (and making sure I didn’t run off from the last aid station at 68km without my poles) and keeping the bottles filled. 

"I shared the track with some champions, not just the ones who were whizzing past me after turning at the halfway point. They all seemed to have inspirational stories to tell and the convos kept me pushing moving forward. Massive kudos to my friends who also ran and smashed it, but more importantly being there to push each other in training and share a laugh afterwards. 

"This race certainly put me out of my comfort zone and into the unknown. When I turned at the halfway stage( the course had to become an out and back because of weather) it was the furthest I had run in training.

"The back half of the race was a slog dealing with an injury and the old brain of yours telling you to either slow down or stop. Super stoked to say I have completed my first in 12 hours 52 minutes. Let me see how the body recovers before I sign up for another one.

Below, we look at five other rugby stars who transformed their bodies to get themselves into top condition.

The Wallabies legend started out as an skinny 78kg teen who worked day in and day out to transform himself, with his size and strength came at a cost, Pocock told Australian Story.

Since retiring, the double World Cup-winner has become obsessed with ultra-hardcore marathons and has shifted a lot of that weight to give him a speed advantage.

The 41-year-old, who weighed 107 kg, is now closer to 87kg since dropping the weight.

For context, that's a weight drop of over three stone.

When he was a prop for the Wallabies Matt Dunning weighed 130kg and was constantly mocked for his tubby frame.

But since retiring from rugby union the 35-year-old has lost a staggering 40kg, dropping from 25 per cent body fat to just 11 per cent in six months.

He looks amazing.

England flanker/hooker Fleetwood was always a fitness freak, but during lockdown she has taken it to another level. She's been documenting her journey, sharing training routines and recipe ideas on her Instagram along the way.
