Dear Muscles,

I appreciate how much you do. I did something crazy last week. In one day, I agreed to complete a sprint triathlon in August, a half-marathon in October, and the Boston Marathon again next April.

I promise to show up if you do...

Cautiously optimistic,
Lauren

Dear Spring,

Thank you for arriving so soon. Did you receive my letters? I've missed you.

Laughingly,
Summer's Sun
