The 15th IAAF World Indoor Championships starts today in Sopot, Poland. The 3 day event is being held in the 11,000 seater Ergo Arena on the border of the cities of Sopot and Gdańsk.

The BBC is covering the championships which is split into morning and afternoon sessions over the 3 days. Coverage is on BBC2 (and online) with extended coverage on the red button.

Jonny Mellor lines up alongside some of the top names in the sport to compete in the 3000m. After coming 2nd in the British Indoor Championships Jonny secured his spot in the team by smashing the club record a week later in the Birmingham Grand Prix and going under the qualifying standard of 7:52.00 with a terrific perfomance of 7:46.73.

Jonny lines up in Heat 2 of the 3000m today which is due to set off at 19:38. Being placed in the 2nd heat means he avoids athletes like Galen Rupp and Dejen Gebremeskel but it places him alongside Bernard Lagat and Hagos Gebrhiwet. The first 4 in each heat go through to the final together with the next four fastest. The final is on Sunday at 15:10.

Good luck Jonny!

After illness sadly meant her not being able to compete in Holland in order to qualify for the Pentathlon, Katarina Johnson-Thompson will contest the Long Jump in this year’s championships.

In the British Championships Kat was crowned National Champion with an (indoor) personal best of 6.75m which was a championship and stadium record. That jump stands as an U23 Indoor British record and the 2nd longest indoor jump in the UK ever; it also ranks her equal 3rd in the world.

The qualifying rounds for the Long Jump start in the morning session tomorrow at 11:15, with the final on Sunday at 14:05.

There is some high class talent in the event this year. Russia’s Svetlana Denyaeva-Biryukova has been jumping well, twice leaping 6.98m in January, and Serbia’s Ivana Spanovic has jumped 6.92m this year, but Katarina won’t be far off those two and has a great chance of a medal.

Good luck Kat!
