Malahide is a great opportunity to do a long seaside run. About 1/2 hour by car from Dublin or 45 min. by the #32 bus. From the Grand Hotel, just follow the R106, about 2 miles south. There’s a bike lane and walkway along the water. At the White Sands Hotel in Pontmarnock, the road turns inland. Here, run along the lovely long beach or continue on the coast road into Pontmarnock and along a pleasant walkway with good views of the water.
