Hi all. I'm a begginer. Please be gentle :P
I've been running for 1 month now. I am currently doing 5km with a pace of about 5:30 min / km. Seems good to me, as I weight more than 100kg (I am 189cm tall).
But a strange thing happened to me the other day - I was running really hard (was trying to catch 5:00min/km mark for the first time) and after I finnished running I had this strange taste of blood in my mouth. I spitted, but there was no visible blood on the floor. I've googled around and read a bit. So was it possible that I was really overdoing myself? Is this good or bad? But to achieve better results I must push myself to the limit (over the limit)?
What do you think?
