You're 90 minutes into a long ride and your legs are fading. You need carbs — fast — but gels aren't your thing and real food is a mess to manage at pace. Clif Bloks solved that problem back in 2005 and have been a staple in jersey pockets ...

Great taste and energy
I use the blocks before I swim early morning - too early to eat a regular breakfast . They taste great, so t upset my stomach and give me enough energy for an hour intensive workout .
Highly recommend !

6 blocks in a pack? Perfect!
Variety of flavors are great. I especially like that it has the perfect release of carbs for my physiology...1 block every 10min, so 6 blocks in a pack = 1hr of ride time. It's packaged well, fits in the jersey pocket ready to go.

Love these chews!!
Of all the chews I have tried; these ate by far the best! I can handle the light caffeine, and you only need a couple to get by. These will be a staple, especially before I swim!
