I don't think Clifbars are give you energy, not a noticeable burst anyway, but may keep a rider from bonking. I use one on a flat 60 miler or a 40 miler with 5000ft of climbing. But really, a P&J sandwich is better IMO, just not as convenient.
I like the cherry almond, walnut raisin flavors. Gina likes the chocolate flavors.
LBS is a rip, $1.59???? Target has several flavors at 99 cents. Also have found great deals at Costco. Gina found a coupon "buy one 24 count box, get one free"!
And the box was on sale for $19.99. That was 48 bars for $20 bucks!
