Once completed, Karl will join the World Mega Marathon Rankings list, with only around 500 other people worldwide who have achieved this number of marathons.
After realising his weight had crept up to 18 stone in 2008, Karl became determined to change his ways and joined a gym.
Nine years later and now a fitness fanatic, Karl is gearing up to enter the elite 300 marathon club when he reaches the marathon milestone in Bournemouth on Sunday 8th October.
“Bournemouth is a special place for me of which I have many fond memories.”
“Following the Bournemouth Marathon in October 2013, I continued to run on average 50 marathons a year and now find myself on 291 marathon completed with Bournemouth confirmed to be my 300th.” said Karl.
The journey to number 300 hasn’t been easy, as Karl recently spent 12 days in hospital undergoing an emergency operation just three months out from marathon number 300.
“After 4 weeks off and tentatively back to running, I’m back on target for Bournemouth to be my 300th marathon!”
If you’d like to join Karl on the start line, there’s still time. Late entries for the half marathon, 10k, 5k, and kids’ kilometre are open until Wednesday 4th October at 5pm and charity entries are still available for the full marathon. Sign up online at bournemouthmarathon.com.
