If your partner trains regularly, particularly for distance events, it can feel like he spends all of his free time running, recovering, foam rolling, cross-training, racing or simply talking about running. Yes, your partner is probably borderline obsessive compulsive, but this is a common trait in dedicated runners; it's what drives them to keep running week after week, year after year. The bright side: Your sweetie likely channels this determined work ethic and devotion to other areas of his life. It might be one of the reasons you love him.
