Finished the Akabane half marathon in 1h44m59s. Not too bad. Improvement of over 20 minutes on the last effort.
But it was the worst-organised event I've ever seen. Seemed like a money-making event, cram them in, forget the rest. 15 minute queues for the toilets. 10 minutes for the luggage storage, which overflowed outside. No fruit or energy on the route. Only two water stops, at 10km and 15km, and they ran out of paper cups for water. I was nearer the front, so got a second-hand cup they pulled from the rubbish bin. Probably more than half the people only got one water stop at 10km. Others queued at 15km using their hands to get water at a hosepipe. In winter, it was irresponsible; in summer, it would have been deadly.
No way will I go back there again.
