HR is spiking high during run...

gr8gorilla - 2010-06-15 12:38 PM I am having similar issues. I had an injury last year and didn't run much until this year. I was running sub 20 5K. Now I can get HR spikes into high zone 4 on a five mile run at a 12min pace. I think the heat is a factor as well as loss of fitness. Each sport has specific fitness. Running and biking help but you still have run to run fast. 

I think it will come back. I hope that by the end of the year I will clicking off those fast 6:30 4 mile tempo runs again. We will see.

Stay consistent. Don't get discouraged. Run More! 

shellabree - 2010-06-15 12:44 PM Very minimal running since February... Miami... the heat... absolutely!  I'm sure all of these things are affected your pace right now.  My average pace during the South FL summer is anywhere from 20-30 slower per mile.  You probably need to expect even more than that right now because you haven't really been running.

How are you with using RPE for a while?  I think that you are going to have to try to ignore your Garmin for a bit.  I tend to go by RPE a lot during our hot summer months.  Keeping my core cool has been helping a lot.  I make 3-4 mile loops around a central location (where I keep a cooler) and stuff ice down my bra, shorts and under my cap.  It works like a charm for about 1.5 miles when it melts away.  Then, I just loop back around again and re-ice.

i think i might actually hit the gym to try to do a short 20 min run see how that goes....

yesterday my run was absolutely frustrating....i left at 6:15 pm and it was still 89 degrees, i had to stop to get a new bottle of water after 3 miles and was soaked in sweat...i guess my pace will be slower...

trix - 2010-06-15 1:33 PM i am not sure if my garmin is having problems or its me....i have a garmin 310xt with the soft HR strap...

i had an injury in feb so have not ran until about 1 week ago (VERY VERY minimal running), however I have done swimming and biking, my race pace is roughly 7 mpm.  anyways i started last week, continued to this week....obviously my endurance has decreased and i fully understand this...anyways....

yesterday I ran 4 miles, after the first mile, my HR spiked to z5, I stoped, took of the strap, put it back on, went down to z3.  after mile 2 of the run, my HR crept up to z4 and just stayed there.

the entire run was slow pace I was running a 9:30 mile pace....in february prior to injury my slow pace was 8:30 and I could run that comfy in z2. 

could it be the heat that is affecting me?  i am not sure at this point by my running is abysmal and any run over 4 miles is simply complete torture....

Only 89F but the Heat Index was a lot higher.  I left work at 9:30pm last night for a 6 mile run home and the heat index was 92F and I'm 2.5-3 hours north of you (which means nothing this time of the year).

I too am recovering from an injury and just started running again ~3-4 weeks ago and am going by RPE only.  HRM in the summer for me is only for fun but during last nights trot top of Z1/low Z2 was at ~9:15 pace, compare that to ~8:00 pace in 50F this past winter in 1/2 mary shape.
