I have been training for my first sprint tri. I had been neglecting my running, so I decided to enter a few 5ks to get myself motivated to train harder. It worked, and I entered my first one last Saturday.
I am 31 y/o, 6'2", and 215 pounds. I started at a good pace, and was at the turn around ahead of my target at 12:13. I ran good for the next half mile, and noticed I was soaked. I looked down and my heart rate was 206, way above what I thought was my 189 max. I paniced and backed way off. It took nearly a minute and a half for it to drop below 195, and I didn't return to stride until it was below 189 again. I finished in 26 minutes, and lost about three minutes "cooling down" my heart rate.
My question is my max heart rate is obviously above 189 as I ended up averaging 195 bpm for the run with a high of 206. I need to train above 80% of my max, so is my new max 206? I wasn't in distress breathing wise, and my legs didn't fail me or anything, my mind is what paniced. Thanks for the help.
