Athletics:Ireland's Jamie Costin and Colin Griffin both dropped out of the 50km walk at the World Championships in Berlin this morning.
The pair was among 19 of the 50-strong field that did not finish the event, despite surprisingly favourable conditions in the German capital.
Sergey Kirdyapkin regained the title he won in Helsinki four years ago despite suffering a bit of a wobble half way through.
The 29-year-old Russian clawed back a 36-second deficit to rejoin the leaders at the 35km marker and went on to win comfortably in a time of three hours 38 minutes and 35 seconds.
Kirdyapkin, whose time was the fastest in the world this year, was followed home by Trond Nymark in a Norwegian record of 3hr 41min 16sec with Spain's Jesus Angel Garcia finishing a further 21 seconds behind.
