Mark Twomey is part of TheBMXDays, a group of friends from Dublin who took up BMXing in the last five years and have since gathered a following on YouTube and Facebook.
Here, Twomey discusses how he got into the sport, what the community in Dublin and Ireland is like now, how the opening of new skate parks is contributing to its growth and the financial costs of the hobby.
