Tired and Energetic after long bike rides (> 30 miles)

[burtonator]

... I'm transitioning to longer rides as I'm trying to maybe run Iron Man and need to be able to do > 100 miles.

Yesterday was 35 miles and for the most part I was fine. Was slightly lethargic on the way back but not terribly so...

Anyway, the WEIRD thing that happened was that I became VERY tired yet energetic that night.

I really wanted to sleep at like 7:30 PM (which is like 4 hours before my normal bed time) but I just couldn't

It felt like I took a depressant and a stimulant at the same time.

Anyone know what's up here? Will this just go away? Do I need to modify my diet?

I have the same issue and never found a good answer to this.
