I don’t know any weight numbers of the two and certainly won’t speculate. But a trained overweight runner will still easily beat an untrained slim runner in a short distance race like a mile.
At distances longer than marathon, BMI becomes a pretty good performance indicator, but that’s not true for anything that’s still close to sprinting distance. If you watched the Boston marathon yesterday, there are no 250lbs+ people breaking 3 hours, that’s just not happening. In the 40 yard dash at the NFL combine, you can see offensive linemen run sub 5 seconds.
Rule of thumb says that an extra pound of fat slows a 6min/mile runner down 1-2 seconds a mile. So somebody who can run a 6min mile at race weight will still be under 7min if they gain 30lbs. Getting from untrained runner to sub 7min/mile is not an easy task for a female runner even if they are already at what’s considered race weight. Especially if they are 25+.
