I started running 15 weeks ago from doing zero activity/cardio in years.
I started with c25k app condensed into 5 weeks then did 5-10k app again condensed into 5 weeks. Past 5 weeks I’ve extended my long run and have just run 13.1 miles in 2:28 this was during an LSD run running that felt tough but leisurely/doable/sustainable it was mainly for time on my feet.
My PBs are 10K 1:08 and 5k 28:23 bout 3 weeks ago. My distance and speed and cardio are improving every week but my fitness is lacking so bad. For example my 5k time I felt so out of breath as though I wouldn’t have been able to keep that pace up for much longer. Which is actually a lot of people’s easy run speed.
I have just signed up for a half marathon in October and wondered what a realistic time I should aim for.
Also how should I approach the next 11 weeks? Speed work? Further distance mix of both?
I was planning to add another days running and increase my weekly runs from 20-25 miles to 30+ miles.
Doable or crazy?
Thanks in advance
