We seem to be in a similar boat. I haven't tested my power much because I've been riding my roadie, but have logged a lot (for me) of running. What is your current weight? I would be ecstatic if I could pull off a 6 to 6.30 mile. I hit the wall at 215 and have dropped to 198 to 200...pretty happy.

Good luck. I personally have gained a total of 50 pounds since my rail think says days of 160 to 165.

I was 94-5 kg on july 9th.

I was 84 kg yesterday morning

Target is 68-70.

This will be the second time in 3.5 years i have gone from 95 kg to 70 kg which is completely idiotic.

My experience was that each pound of bodyweight was worth about 2 seconds per mile running on a hilly course. I ran the same hilly half-marathon 4 years in a row. Basically the same training each year and presumably fitness level, but I gained weight over time and my time were slower pretty much close to a minute per pound for the half marathon.

Generally speaking after about 6 months of serious training you'll probably be fairly close to your potential (most research studies show VO2max peaks after 3 to 6 months of training). Not that you won't get faster but huge gains probably aren't on the books. This has been my experience too observing newbies coming into endurance sport, people who are going to be fast are pretty fast within a relatively short amount of time with serious training.
