I didn't have a bad run today, I had a terrible one, does it get better? I'm in my early 30's, I'm fairly new to running, this week I finally completed C25K, I manage to run 30 min straight, but I only make about 3.5 km because I'm so slow, everyone passes me by, I've been telling myself it will get better, I'm just starting, that the area is really hilly so it's not like I'm exercising, etc. But today I wasn't even 15 min into my run when I lost my pace completely, I just couldn't recover my breath, I had t walk and I just felt so defeated. Does it really get better or am I just too old for this and I should settle for a 45 min 5K if I'm lucky?
