1) World Athletics is way better than IAAF so all in all this is a good idea.
World Athletics Championships etc is just easier than "IAAF World Champs".
Seems like slowly the IAAF is trying to implement some change which is great. Having a more modern name, logo and promoting head to head matchups is a good thing.
Granted some of the changes are off the mark. (ie possibly putting in a 3k instead of a 5k at Diamond League.) But I can give them the benefit of the doubt. Still think with DL changes it might be best to have less of each event in the DL than scrapping some events entirely. 400 hurdles is hot this year, but was an afterthought 2 years ago. Say the changes had come in last year and it was scrapped, then fans would be missing out on one of the best events this year. Same thing say with long/triple jumps sometimes.
2) Agree with poster above that they could have made a much better video. And why put "Walk" before other stuff? They're trying to modernize the sport. People who are going to be drawn to sport by a new logo are going to want to see cool competition highlights, etc.
3) How do we still not have the situation with the Olympic Trials sorted out yet? A total lack of leadership by USATF but to a lesser extent IAAF. They say they are trying to promote head to head matchups. We have an Olympic Marathon Trials with millions of $ invested in it and there is a simple fix to allow it so the top 3 make the team, yet they still haven't done it. Unbelievable.
