im a beginner runner training for my first 10k in 4 weeks. When i try to improve my speed i get too out of breath but my legs feel ok. How do i address this in my training? Do i need to run further at a slower pace or more short fast intervals?
Ive been running 5-7k four times a week plus the gym and this doesnt seem to have improved it at all
Sorry if this is a stupid question or im not explaining it properly.everything ive read talks about " heavy legs" but i cant find advice for croaky old lungs
