Chris, 33, ran the same way from his home in Chapel Allerton to Roundhay and back for 50 days from January 1 because he wanted to challenge himself mentally as well as physically while raising cash for a good cause.
Chris ran a half marathon on the 51st day of his challenge and a 50K ultra marathon on day 52.
From day 53 to 99, he ran distances varying from 6K to 22 K and on the final day he completed 105 laps of the running track at Temple Newsam to complete a marathon in a personal best time of 3:29.
Chris clocked up a total distance of 1,075 km over the 100 days and has so far raised more than £1,000 for the Alzheimer’s Society.
He chose the charity after both his grandfathers - Kenneth Brame and John Sutcliffe - died aged 93 and 79 respectively after being diagnosed with dementia.
Chris, who works as a personal trainer at Graft Haus gym on Kirkstall Road, Leeds said: "The daily running challenge has been tough, especially doing it through the winter months with the snow and ice.
"With the gym I work at closed down due to the pandemic I decided to take some time and focus on my own fitness goals, whilst trying to raise money for a worthy cause.
"I also wanted to see if I could run through the whole of lockdown number three until the gyms re-opened, which I managed to do.
"Being a personal trainer, I’m extremely passionate about getting people moving and inspiring others to live a healthier lifestyle.
"Our physical and mental health has never been more important right now.
"Overcoming big challenges is a welcome mindset boost and proving you can accomplish your goals gives you the self-confidence to keep coming back for more.
"Having seen both my grandfathers suffer from dementia, I really wanted to try and raise more awareness for this charity.
"I can only imagine how tough it must have been during the pandemic for so many other families who have a loved one suffering from dementia."
