How much faster can I expect to run my 10 K races when I've lost 10 kg (18 lbs) per September 1 this year, compared to when I weighed 80 kg, in March of this year?
I'm an experienced runner (16 years of more or less continuous training), male, 54 years old, who got injured in 2010 and gained a lot of weight, which I'm slowly trying to lose over the years (about 10 kg, 22 lbs, per year, started in 2013).
My current weight is 78 kg, 174 cm long, which gives me a BMI of 25.8. My current fastest recent 10 K race result is 46:02 minutes, half marathon 1:45 hours. That was when I still weighed 80 kg (176 lbs), BMI 26.4.
I'm training daily, around 60 km (37 mi) per week, one interval session, one intensive training run between 10 en 15 km, several easier sessions (for recovery), and a race or test run every week. I don't feel tired or over-trained.
