My dh goes running twice a week. He has recently been working hard on increasing his distance and currently runs around 12km at each run - this is the furthest he has ever run. He has randomly decided to take the morning off work tomorrow and run a half marathon - not an official race, just go on his own to attempt the distance. I am very worried about this - he will be alone, we live relatively remotely and the route he has planned is along country roads, so he is not going to have people around him, he has done no specific training to gear up for it (just his 2 runs a week) - he basically has not prepared at all! I asked him about carb loading and he struggled, I asked him if he even had a drinking bottle to take with him and he said no (he doesn't take a drink with him usually)! I think he is being unreasonable! I have no problem with him tackling the distance, but I feel he should do it for the first time at official race, with medical help and people nearby, having done some specific training and preparation! He thinks I am being unreasonable and am spoiling his mindset by being negative!
