Running

Speaking of fast marathons, I wonder, is there anyone in here who can beat me for slowest marathon time? I did my first one, on a flat course on roads, in 5 hours. Was aiming for under 4h but it was an absolute disaster on the day; I knew it was going to go horribly wrong within 3 miles

Edit: slowest time in a mostly-road marathon, that's the challenge. DNFs and mountain marathons are out.
