The 50-year-old said he could not believe that so many Cobblers fans would turn up to support him.Brady, from Australia, spent three and a half years managing Northampton, and took the team to League One in 2023.He resigned in December 2024 after the Cobblers went six matches without a win and dropped into the relegation zone.
Brady told BBC Radio Northampton he thought he had recorded a quicker time than the official one at the event because he had been following one of the pacing runners who wore flags showing their expected finish time."I was aiming for 3 hours 45 minutes and I followed the flag-bearer who had [that time on their flag], and I was about 30 seconds behind him all the way in," he said.
"But I think even some of the guys with the timed flags flagged themselves.
"I was thinking, 'I'm right on time here,' coming in, and I came in at four hours and three minutes."The gas released during the process is also collected for energy use.
