I'm awake just before 5am, trading sms messages with Z about how he's outrunning me and I felt like running at 6am. He thought I'm insane by artfully ignoring the fact that he ran despite being unwell. God, how I want to pull off a Forest Gump right this instant. Is there an unhealthy addiction to running and if so, can it be cured by prescribing sleeping pills so you doze off before you hit the tracks?
