Welcome to a very special Christmas episode of 4 Feet Running, episode 23! This week: - Nice: Nik and Dan and their dogs go for a 3-mile slog down the slushy median of Commonwealth Avenue in Boston - Naughty: Dan doesn't do so well at it - Nice: Nik discusses her plans to do not one but possibly three marathons in 2008 - Nice: She also is planning to run various and sundry other races and do an icy New Year's Day ocean plunge - Naughty: Speaking of things that are cold, Dan is super-grumpy because of bladder issues, traffic, and a startling lack of holiday cheer - Very naughty: He restores it by trying to peek at his Christmas presents - Very nice: They read some e-mails and mention some fans' blogs (12.24.07)
