I was just going to write about MY ride this Saturday which sounds pretty much the same!! I ate a bowl of puffed wheat for breakfast (no protein and not much carbs) and then went for a ride...I forgot my Clifshots so had nothing but water with me ( I SO know better!!)... it was hot, really hot and humid. I was doing fine, then some guy caught up and tagged on along side me... we rode together for about an hour at about 18mph... faster than my norm on rollers!

Anyway, 25 miles came and my legs were feeling like rubber... so I stopped and got a bran muffin and juice... but it was too late. When I started back up my legs were like wood... I finished at 14.37mph avg... and the last 3 miles is a BIG climb up North Torrey Pines Road...OMG... I was really, really glad to get off my bike... and had no desire to ride Sunday either! UGH!

Sorry you had a dead legs day too... I feel for you!
