What does an athlete do after winning a world title? Treat herself to four puddings, it seems. "Yum," Jessica Ennis-Hill simply said in her caption on Instagram., external

It wasn't only sport scientists and former athletes who doubted whether Jessica Ennis-Hill would be the heptathlete of old. There was a time when her coach Toni Minichiello wasn't so sure...

"What an amazing role model Jessica Ennis-Hill is. It is about building back from having a baby.

"She has had to build up her training and do everything right, but she has peaked at the right time. She said she would be happy with a bronze medal but what an amazing job she did.

"She is so happy being a mum and her son is going to be so proud of her."

Sometimes no words are necessary. The Guardian sum up Jessica Ennis-Hill's feats in one glorious image. 

Sean Ingle writes:, external "Only a handful of women have celebrated a world title after giving birth, and the majority of those have come in endurance races, where pregnancy may confer some benefits. But in the heptathlon? Never."

We've not talked much about Jessica Ennis-Hill yet. Let's address that. 

Thirteen months after giving birth to her son Reggie, Ennis-Hill is now a world champion. A remarkable achievement. 

The 29-year-old started her comeback on a stationary bike in November, was then troubled by an Achilles injury. There were doubts whether she would compete in Beijing, but GO to the Chinese capital she did and my how she triumphed. 

But what do you regard to be the greatest comeback in sport? Is Ennis-Hill top of your list? Tweet us your thoughts using the hashtag #bbcathletics or text 81111. 

It's that man again, the one who saved athletics. "Usain Bolt gave the gift of life to athletics as he produced surely his greatest win to raise the sport from its death bed," writes Alex Spink in the Daily Mirror. , external

I think it's universally agreed among headline writers that Usain Bolt is the saviour of athletics. 

"Usain Bolt rode to the rescue of his beleaguered sport once again as he dashed Justin Gatlin's hopes of 100 metres gold at the World Championships in Beijing," says Guy Aspin in the Independent.   , external

"Usain Bolt does feel responsible and people were depending on him. People appreciate him and what he brings to the sport. He is an entertainer but he takes the sport very seriously.

"It is impossible to ban people for life. That is what the fans want, but legally it is not possible so we will have to accept that drug cheats will come back into the sport. For the fans of this sport, the sentiment was they would have preferred it if Justin Gatlin had gone out in the first round."

Roeland Meijer:, external For the love of sport, I cannot understand why lifetime bans are impossible to enforce. In other words, cheaters/criminals win.

"On the morning after the night before, all the talk in Beijing - or at least in the sporting bubble around the Bird's Nest - has been of a 100m final that still has all who saw it shaking their heads in wonder. 

"Why did Gatlin fall apart? Where did Bolt find the self-belief? How critical were the mind games that the Jamaican tried on his rival as they warmed up? 

"There is even a theory it came down to a fistbump, offered by Bolt to his rival seconds before gun. Linford Christie once growled like an angry bear at Carl Lewis when he tried the same thing before a World final. Gatlin, nonplussed, accepted it - and in that moment, goes the theory, subconsciously ceded control and authority to the great champion." 

The 100m final was close, there was hardly anything in it, just a hundredth of a second separating Usain Bolt and his rival Justin Gatlin but that was enough for gold in what has been described as the six-time Olympic champion's greatest performance of all. 

Gatlin was the favourite, he'd run the four quickest times of the year, but that accounted for nothing in Beijing. They don't give gold medals based on Diamond League performances, and the majority of the world is happy about that. 

"0.01 secs between good and evil as Bolt pips drugs cheat," headlined the Daily Mail today.

Unsurprisingly, Usain Bolt and Jessica Ennis-Hill dominate the back pages of this morning's national papers. "The day athletics smiled again," headlines the Daily Telegraph., external

Live coverage has started online and on BBC Two with Gabby Logan, Michael Johnson and Jo Pavey. They'll be with you all afternoon.  (Hang on, no Daley Thompson? Where's Daley?!)

Was Bolt's victory on Sunday his greatest miracle, asks our chief sports writer Tom Fordyce. 

"Once again, Bolt proved us all fools," he writes. "On a night that could have ended with the sport no longer teetering on the abyss but plummeting over it, the victories of Bolt and, a few hours earlier, Jessica Ennis-Hill in the heptathlon, gave the believers something to cling to and the doubters reason to perhaps think again."

Hello! Welcome to live coverage of the third day of the World Championships in Beijing, but we can't talk about today until we reflect on a wonderful yesterday. 

Jessica Ennis-Hill produced the mother of sporting comebacks by winning heptathlon gold while Usain Bolt pulled off what seemed impossible, beating Justin Gatlin, a two-time drug cheat and the dominant force of sprinting in the last two years. Incredible performances from incredible athletes. 

The sun rose again this morning, as it always does, and the clocks continue to tick. Everything seems the same, but something's a little different. Worriers are smiling, skeptics are filled with hope. The smiling assassins of cynicism triumphed in Beijing yesterday and dark clouds are gradually disappearing.
