Seeing Great Britain's men's 4x100 metre relay team mess up in their heat was sad to see, but hardly surprising.
At so many major events this season the teams in both relays across both genders have either dropped batons, run outside their lanes or made changeovers in the wrong places.
It has become the British athletics equivalent of penalty shoot-outs for the England football team.
What makes it even worse is that they ran so well. Dwain Chambers down the back straight was great and young Adam Gemili was blistering on his anchor leg — once he finally took the baton from Daniel Talbot, anyway.
If there is some good to come out of this, it is that young Gemili will have learned a valuable lesson right at the start of his career. Hopefully he will look at his part in the botched changeover and be horrified by what he sees. If ever there was a reason for an 18-year-old whose star has risen so quickly not to get complacent in the future, this is it.
I have been told by Darren Campbell — part of the last British relay team to win Olympic gold — that tonight was the first time the British quartet of Christian Malcolm, Chambers, Talbot and Gemili had run a race in that order. If that is true, then that is a terrible decision.
Athletes spend so much time training focusing on nothing but themselves, so when they are involved in something that demands they work together with others you need the familiarity that only comes from meticulous and thorough practice.
They may well have run in that order many times in training, but a competition environment is something entirely different. People react differently when they are in an actual race, especially a packed house cheering you on as a home competitor.
How that team was allowed to go out there for such a huge race is beyond me.
I think a big reason why Britain has historically struggled in relays if because, on an individual basis, we so rarely have sprinters who are able to compete with the top competitors in the world. That means there is so much pressure to get the changes absolutely spot on, because they have to make sure they are better than the others just so they can try and keep up.
On top of that, there is a history littered with bungled relay attempts that these athletes would have all too aware of, firstly when they were growing up as young fans of the sport and then when they were placed in that very situation themselves.
Until Britain consistently produces sprinters who are used to the high-pressure situations by reaching major finals on a consistent basis, I am not sure how they are going to break this terrible habit.

Friday was another disappointing day for Britain — although it is important to remember just how rare they have been throughout these Games.
Something that will surely give the hosts a lift on Saturday is Mo Farah racing in the men's 5000 metres.
Every day I have been at the Olympic Stadium, the crowd has been louder than the day before. It is though the people with tickets are seeing it at home and are getting whipped into a frenzy before they even arrive. I can only imagine what the place will be like when Mo takes the track again.
That should not put too much pressure on him. Farah knows the double is there for the taking. He admitted his legs were feeling it in the closing stages of the 10,000m, but he has had a few days to relax now. Britain doing so well in other events probably helped, as the demands of the media were less on him once they had a new bunch of champions to talk to.
It is not a given, by any means, but Farah has it within him to make this Saturday night as glorious as the last one in the stadium was.
