There comes a time when every cyclist reaches into a jersey back pocket, extracts a pro-biotic hyper-nutrient choco-green exfoliant chia protein bar and instead of ripping away the wrapping like the savage carbo-craving road shark she is, she freezes.  Tongue, stomach and heart revolt.  A chilly voice in her head announces the rebel demands: We don’t want to eat an energy bar.  Ever.  Again.  Last year, reflecting on the long PanMass Challenge ride she’d just finished, Jody said to me, “I am sick of f_______ energy bars!  I can’t stand it!  Next year I’m going to make my own.”  Fortunately, she reconsidered.  And that’s why you’re being treated to Bicycling Spring Rolls this week.
