I do know one thing- after dropping about 13 pounds so far, I have a particular route I chose to take and clock myself on. At first, I was only able to do the route in like 3 and a half hours. Now, at 13 pounds lighter, I'm able to do the same route in 2 hours and 25 minutes. I'm now working to get the next 10 pounds off and see if I can get down to 2 hours.

I'm not clear on all you are doing, but from everything I've been able to find on how weight affects speed, I don't think a 28% improvement can be because of a 13 lb weight loss. For example, one source I had said a 10 lb weight reduction would save only 33 seconds over a 20 mile course (various terrain).
I suspect that as you are losing weight, you are also building muscle and skills which makes the main differences.
