And on that note we shall sign off.
Lord Coe: "We need to grow the sport and the fanbase. We need to co-ordinate the calendar, it is cluttered.
"We have come from a long way back. This is going to take time."
Does athletics need an official ranking of athletes like tennis?
More from Lord Coe: "One of the things that has frustrated me is that we are one of the few sports who can't say who is the number one long jumper? Who is the number one 800m runner? You can call it a league table, a ranking.
"It's not just about times and distances. A number one place can be gained by one great performance. We measure to a hundredth of a second, we should know who the best are by some sort of metric."
IAAF president Lord Coe: "This has been an amazing standard. Some of the athletics has been sublime.
"The crowd rose to it and the 800m was brilliant. The world cup was here last week and that may have played a part in smaller crowds. If you have four days of action in eight days numbers may be down.
"We are trying to create a sustainable system for our sport. The biggest challenge is how do me make the sport more attractive for fans and athletes."
It's good, it's positive that we have so many good athletes. It is tough for the selectors though.
Two good lines there then from Greg Rutherford.
He will NOT be going to the Europeans in Berlin.
And he IS going to try and have a go at cycling.
Greg Rutherford: "I'm 31, which is old in long jump terms but not others. The bike is something I am talking about. I'm not saying that I am moving to track cycling and will be world class but I want to try it and see what happens.
"I might have another bite at the cherry. I am going up to Manchester for testing in the next few weeks.
"I will not be competing in Berlin at the Europeans. I can't train properly, it is not feasible for me to go there and win so let's get rid of that idea."

Greg Rutherford: "Every time I see that footage of 2012 I get emotional. It's difficult, everything makes me cry at the moment.
"It's very much the time to be handing over the flame to someone else. I've thoroughly enjoyed my career. I'm incredibly lucky. Athletes don't get the chance to say goodbye and I did today. I wish I could keep going but my body won't let me."
This was one of the highlights of the day - in fact, of this season so far.
Watch Kenya's Emmanuel Korir run the fastest 800m since the London 2012 Olympic final.

And that concludes the action at the Anniversary Games. A cracking weekend, I'm sure you will agree.
Sifan Hassan: "It's amazing. In the last two laps I felt good so I knew I had to go. I did it, I thought they would catch me but I'm so happy. It's fantastic."
Laura Muir: "Everything's fine, I just went too fast in the first lap, it killed my legs. I was here to go for it and it showed but I'm grateful for the opportunity.
"We've asked to be selected in the 800m and the 1500m for the Europeans."

Laura didn't have the bounce in her legs, maybe there was a bit of hay fever. It's not a disaster, it wasn't a bad run.
The third fastest mile ever ran by a woman. Hats off to Sifan Hassan.
The world record is 4:12:56.

That's an exceptional performance of Sifan Hassan, third on the all-time list.
Laura Muir clocked 4:19:28 - just under two seconds outside the British record.
No British record for Laura Muir but a very fast race!
