I don't have any genetic predisposition for running. I ran my first marathon in 2014 in 4:06, and then two years later in 3:28.
My PB was in 2020 when I was 28 years old - 3:03 on a hilly marathon. I've checked Training Peaks - my weekly running mileage in the ten weeks leading was as follows: 31, 24, 29, 13, 28, 30, 25, 38, 29, 23.
I trained on the bike (both indoors/outdoors) for around 7-8 hours per week, and did some swimming too (not more than 4 miles total).
I know it would be very hard for me to run more (both mentally and physically, as it could lead to injuries) than 40 miles per week, so I prefer the cross-training approach.
This year I've been running no more than 27 miles per week and ran a half marathon in 1:25, which translates to a potential sub-3-hour marathon. Average bike is also 7 hours/week (with Z2 and quality Vo2 intervals)
I believe my running form is similar to that of 2020, or a bit better.
