Hi there,
I ran 6 X 1 mile repeats today with 90 seconds rest: 5:46; 5:31; 5:38; 5:42; 5:38; 5:42. I am curious to know if a sub 1:20 half in three weeks is a reasonable goal based on my fitness.
Some other details:
-I'm 29 and am new to running as of November 2018. At that time I ran my first 5k with virtually no training in 20:51.
-I ran a 17:41 5k on July 1, 2018.
-I've gradually increased my mileage since starting in November from around 30 miles a week to an average of about 75/80 miles over the last two to three months.
-I run easy 15-18k three times a week; two workouts (e.g. 6 X 1 miles repeats; 12 X 800m; etc.); two easy 10k runs (doubles); and one long run of 25-30k.
Thanks!
