Low HR Training

    So, the temps have dropped here in Utah this week. At the same time, my pace has picked up for my runs. Here is some data from the same route, one run yesterday and one 2 weeks ago: Yesterday 6.1 Miles 54:04 8:51 / mile Avg HR 136 Max HR 146 33 F Humidity 79 1 8:39 1.00 7.5 129 141 120 2 8:54 1.00 7.6 133 140 121 3 8:35 1.00 8.2 135 142 123 4 9:14 1.00 7.6 140 147 122 5 8:53 1.00 7.1 140 145 121 6 8:50 1.00 7.9 138 143 122 7 0:56 0.11 7.5 140 141 14 Two weeks ago (9/29) 6.1 Miles 56:04 9:12 / mile Avg HR 137 Max HR 151 52 F 1 8:54 1.00 7.6 127 141 119 2 9:01 1.00 7.1 134 141 121 3 8:56 1.00 7.7 138 143 123 4 9:51 1.00 6.8 141 151 123 5 9:22 1.00 6.9 140 146 122 6 9:10 1.00 7.9 142 149 121 7 0:50 0.10 7.4 144 147 12 I went from averaging 9:15 to 9:30 on my sub-MAF runs to a sub 9 minute mile average for my first time ever with low HR training! I was so happy. I thought this might be a fluke. So, I went out for 8 miles this morning. My average pace today was 8:40 / mile. Last week, the same route was about 9:20 / mile. I know my HR shoots through the roof on hot days but this was new to me. Anyway, I'm not sure if it is the change from 50+ degree temperatures to 33 degree temperatures or if there is something else at play. I saw similar changes going from my elevation (4700 feet) down to sea level but this cold running effect is new to me. Comments? Do you experience similar things? Or is this just a coincidence and my slow twitch happened to blossom at the same time as the winter frost? Big grin Whatever it is, I hope it stays. It was so nice to glance at my watch and see I was cruising along at an 8:20 pace while being well under MAF. Such a nice change from forcing myself to slow down to stay under MAF... BTW, a hearty thanks to all the gurus here (I was lucky to follow over from CR). After not being able to turn myself over in bed due to an SI joint issue last winter, I am finally back to 40mpw. Here's looking forward to my first marathon next year.

    Just because I look dumb doesn't mean I'm not...

      Yes, indeed, don't reset your dial - as it gets colder, your HR will get lower and your pace will get faster! It's a bit exciting.

        I think I might be a sea cow, so please stay away. Don't eat me. That being said. I usually don't see huge differences between 50º and 30º, I do when it's 50º compared to 70º. Here's a little chart: Pace Loss Due TO Heat 55-60 degrees.....1% 60-65 degrees.....3% 65-70 degrees.....5% 70-75 degrees.....7% 75-80 degrees.....12% 80-85 degrees.....20% above 85.....forget it, run for fun The less heat there is, the less stress is being put on your body to stay cool. You'll also might progress faster in colder weather than hot for the same reason (depends on the person and how their body handles heat). Keep going! --Jimmy
