Just got off the phone to my dad. I remember him doing a marathon years ago, but I didnt really pay attention to him them, so I asked him about it.
He must have been in his late 50´s, it was actually a half marathon (21km) and he came last! They were packing up as he came across the finish line! Hes just amazing! He told me he got so tired, that he ended up walking the last bit, hense him being last. But he finished it. He wanted to do the full marathon one day but hes proud of this achievement. Me too :-D
