The race organisers have posted a video of the 2012 course. You can take a high-speed tour from the start on Fitzwilliam Street along the whole route and back to the finish at Merrion Square.
Compared to the 2011 edition, the only significant change to this year’s Dublin Marathon route is that runners will now go up the centre of the Phoenix Park along Chesterfield Avenue, which was closed for road works last year, rather than going around the edge of the park. This means that the 2012 course reverts to the same one used in the 2010 race.
I recall some suggestions from around the time of the race launch earlier this year about taking out the Roebuck Road section of the course – the only serious uphill section of the race, coming at the difficult 20-mile point. But Dublin’s version of Heartbreak Hill is still in the marathon, something that may not be good news for many who’ve struggled at that point in previous races.
Here’s the high-speed tour of the 2012 Dublin Marathon course. Get visualising!
