"As important to the eventual destination of the gold medal in the heptathlon as KJT's last-ditch clearance of 1.80m in the high jump or JEH's lead after two events may have been the disappointing failure of favourite Brianne Theisen-Eaton to clear the relatively modest 1.83m. 

"Already 87 points down on leader Ennis-Hill, her PBs in the Saturday's remaining events, the shot and 200m, are inferior to Ennis's by almost a metre and half a second respectively, with Johnson-Thompson also quicker in the 200m. 

"What we don't yet know is how fit KJT really is or quite how much flat speed JEH has in her legs. If the competition has started well for the Britons it is still wide open."

There's no better feeling than waking up on a Saturday morning to news that two of Britain's most recognisable athletes have been setting the pace in the heptathlon. 

Olympic champion Jessica Ennis-Hill leads after two events, while Katarina Johnson-Thompson is second - although it was a dramatic morning for the Liverpudlian. 

Johnson-Thompson needed three attempts to get over her opening height of 1.80m, having hit the uprights with her head on her second attempt. Failure on the third attempt would have ended the 22-year-old's medal hopes. Der-dum, der-dum... But she salvaged 1.89m from the high jump despite struggling with her run-up. Hooray!

How to watch the world's best in Beijing? Buy tickets, perhaps? But if that isn't possible there are a number of other ways. 

There's live coverage on BBC Two and online from 11:05 BST. 

But if you enjoy listening to Mike Costello and Darren Campbell (who doesn't?) tune into BBC Radio 5 live  via this page. It goes without saying there'll be live text commentary throughout the afternoon. I hope that's covered all the bases.

Hello! It's the opening day of the World Championships in Beijing which means after weeks of talking about doping, doping and doping we finally have an opportunity to watch some running, throwing and jumping. 

Blyton would not have written the stories which have made for harrowing reading for athletics fans in recent weeks - suspicious drugs tests,suspensions, it goes on and on - but perhaps over the next week or so extraordinary performances will help clear those dark clouds.

After a stormy summer come the performances which will herald blue skies and sunshine for the world of track and field. The crises will be forgotten, enthusiasm restored, as athletes cross the finishing line with their arms aloft in triumph, lighting up Beijing with their incredible feats. Or so it would be if we lived in an Enid Blyton sort of a world.
