Hi - Anything is possible if you train sufficiently.
Within 18 months i went from 162kg (male at 189cm), to running the melbourne marathon this october (42.2km run in 3hr54min). My weight at the end of the marathon was 89kg. It took me approx 12 months to loose the weight (mainly from bike riding) and then i started running. In jan of this year i could run approx 4-5km so i just built up from the there
1st fun run was run4kids (15.2km) then age run to the g half marathon (21.1km) and then the melbourne mararthon (my 3rd fun run lol
; but seriously, for me it was all a mind game getting up at 5am in the morning to run laps of the tan (trained up to 70km running for the 3 months leading up to the event) is not everyones cups of tea.
My motivation was a fatty liver, no energy, and the fact i knew i was mentally strong. I did not weight myself for ages and one day i did and a male at the age of 27 weighing a cool 162.2kg was scary so i got off my arse and did something about it ! Signed up for the around the bay ride (210km ride), kept up a reasonable diet, cut back of the booze and away i went !
