I'm pretty happy, did 14 miles today and I'm not feeling it too bad. Just curious because I didn't see an expiration date, but is there usually one for Clif Energy gels? I had two and used one today. Best case, I got them while running the LA Marathon in March 2017, otherwise they were from the WDW Marathon in 2016. Seemed to work ok. Right after, I went to the running store and they didn't have Clif gels, but had GU. Is that pretty similar to Clif or any major difference? They also had Jelly Belly energy jelly beans. Has anyone tried these before? Thanks! I'm getting excited! I laughed because I did the Dallas Turkey Trot 5k on Thursday and they have an 8 miler option, and I thought about doing it and then realized it wasn't a long enough training run for me at this stage.
