In Peter Snell's book, he said it takes about 2 years to develop your aerobic capacity. I think it's probably best if there isn't much in the way of racing and hard workouts during that period.

This was my experience. I didn’t start running seriously until middle age.
The first year of training I made substantial progress. The second year, significant. By the third year I was close to the top of the learning curve and was only making marginal gains.
