Second was the Wanganui Harrier's men's team (4m 29m 53s) with Feilding Moa Men rounding out the top 3.
WHC spokesman Bill Charnock said Al's Mob from the Manawatu Striders finally managed to win the walking relay in their 14th attempt, beating perennial favourites Taranaki Race Walkers by almost 12 minutes.
The Trentham Harriers walk team chased the Taranaki team all the way to town, finishing third by only 41s.
In the individual race, Antonia Johnson was the winner, having come out to compete while on a visit home from Edinburgh.
She completed the course in 7h 8m 6s, around 12 minutes ahead of Scott Thompson with Carl Laffan in third.
"Mention must be made of Perry Newburn from Feilding and Wellington's Marcelo Vanzuita who both completed a 'double running' of the event," said Charnock.
"Starting late Friday and running through the night to arrive in Marton in time to have a short rest and head back to Whanganui with the rest of the field.
"Perry is no stranger to extra long distances, having run across the USA, while Marcelo is training for a 700km event in Alaska early in 2017."
In the Under 20 relay, staged over the 26.76km in the last four legs of the full event, the first home were Big Juniors Wanganui in 1h 44m 5s.
Wanganui Junior Rockets came second followed by Manawatu Striders Juniors.
