When a woman is undoubtedly flattered by a charming man, she experiences the symptoms of Marathonitis. Symptoms include uncontrollable smiling, giggling, nervousness, and many similar feelings related to flirting. There is no cure for Marathonitis. Once you have acquired Marathonitis, there is no turning back.

Girl: *blushes* Thanks Puppy :)

A footrace of 42.195 kilometres, which is usually held on roads. It's featured at the Olympics and the World Track and Field Championships. The race was borne out of the death of Greek army messenger Pheidippides, who ran from village of Marathon to Athens to inform the Athenians of the Greek's victory over the Persian army. Pheidippides died upon delivering the message.
