Plenty had him in the mix for the top five, but not many would have been brave enough to project a win for the Australian.
On Saturday, in near-perfect trail running condition, Shatrov went about proving those doubters wrong in a performance for the ages, not only taking out the 100 Mile event but in the process smashing the race record of Jeff Browning (16h 18m 54s in 2019) by going sub-16 hours with a time of 15h 53m 30s.
The 41-year-old surged into the lead early and only held his form to leave a world class field trailing in his wake, with runner-up Yoshihiko Ishikawa (Japan) and Adam Kimble (USA) finishing well behind the flying Aussie.
"This is number one, a massive achievement. Most of you know the way I run, I tried to modify that today. I started a bit slower – I thought. I just ran comfortable and felt good and just kept going.
In the women's race it was a similarly dominant and somewhat surprising performance from winner Ailsa MacDonald, of Canada, with the 39-year-old upsetting her more fancied rivals to finish third overall and a clear winner.
"It is pretty amazing, I am pretty happy, I wasn't expecting this today, this is a surprise," MacDonald said.
"I had a good build-up coming into the race and I always race really well at this time of the year, I thought I had a good shot coming in but to place top three overall was beyond my dreams."
Perhaps part of that success came down to a very relaxed game plan, putting little pressure on herself to perform.
"I didn't have a plan other than to go out and enjoy the day and take the punches that were thrown at me. I had lots of low moments during the day like everyone I am sure, but I had lots of high ones too. The crowd was amazing, the crowds, scenery, aid stations, everything was just amazing."
The field was left in MacDonald's wake as leading contenders first fell off the pace and then for many, withdrew from the race altogether, but competition for the other spots on the podium was intense, with Caroline Sebert (France) just doing enough to hold off an amazing performance from Rotorua local Sue Crowley with just 14 minutes between the two.
