If your hallway is constantly covered in mud, dirty lycra and those weird little tubes of energy gel, you’ve just found their perfect birthday card. If there’s one thing runners love more than running, it’s telling you that they’re going for a run, just been on a run or are thinking about going on a run. They’ve got a hobby, though, and it’s better than collecting Pokemon cards, right? Give this card to your no.1 runner to wish them a hap-PB-birthday (get it? lol), but do it from the comfort of your sofa. Running’s hard. Maybe they’ll celebrate by going on a run?
