This October will mark the 10th anniversary of the Cardiff half-marathon, and this year it promises to be bigger than ever.
At a special launch event later today, organisers are expected to announce that more runners will take part in this year's race.
They are also planning to announce a new route which starts and ends right in the city centre.
A new route for the marathon is also expected to be announced later this morning, as well as an update on the race capacity and future plans for Wales' biggest road race.Last year's Cardiff half-marathon was a sell-out race with a record fifteen thousand runners taking part.
The event has grown considerably over the years and now attracts both UK and international runners – it is now known as one of the top events in the Autumn running calendar.
The 2012 race has been set for 14th October.
Last year, fifteen thousand runners took part in the Cardiff half-marathon this morning.
Nearly five hundred charities are expected to benefit, with more than a million pounds being raised.
