Dan Armstrong, from Kingswood, took part in the Lost Hours Walk, part of the Campaign Against Living Miserably (CALM), as a tribute to his brother Gavin.
Dan, who works for the Edenstone Group, decided to walk between the company’s two offices – from Magor to Portishead – just weeks before the charity challenge.
“Luckily my father-in-law is a retired colonel and a keen walker and helped organise the route. It’s only a 20-mniute drive between the offices, but walking it is completely different,” Dan said.
“We kept a steady pace and finished in under 12 hours. I usually only average around five thousand steps a day so in hindsight a bit more preparation would have helped before walking almost 59,000 steps.
“We had estimated the route as around 27 miles but in reality, it was almost 31 miles.”
Chelsea fan Dan wore his brother’s Liverpool FC kit during the walk, which he says would have given Gav a laugh.
