Coming up this weekend in Edinburgh is the 2010 ITU World Duathlon Championships (www.edinburghduathlon2010.com).

One member of a strong GB ladies team was due to be ETU European Championship bronze medal winner Kat Grimmett, who made such an impact on the sport in 2009, and but for an unfortunate crash in sight of T2 last year could well have been the defending ITU World Champion this week.

However, Kat has now decided to retire from the sport of duathlon slightly earlier than planned, and focus fully on her running career, where success over the marathon distance is her ultimate aim.
