Is joining “Fun Run” addictive?

I guess this is true. My hubby found his new hobby just last June and that is joining “Fun Runs “ . For a month now, he has joined 3 separate events. The images above was his first entry during the Freedom Fun Run in celebration of Philippine Independence Day. From the 5 kilometer run, he raised his level by running 10 Kilometers last week . He is planning to join the 21 Km run this July 29. No he is not aiming for trophies  or medals , but he’s just want to challenge his capacity. To prepare for this event, he’s doing marathon exercise everyday at our subdivision’s park. A ctually, he invited me to join the run, but I doubt if I can survive running even one kilometer.
