Hi again,
The race was already a week ago but I have not looked at collected data yet.. I have to correct this mistake.
Currently I am collecting training and race data with two devices/sources: Polar RS800CX watch with S3+ footpod and miCoach train & run application on my Windows Mobile phone. Unfortunately the miCoach app failed to work under lock screen during this race event. Now I have a fastest kilomter record in my miCoach account with time 0:00:03... Hope the miCoach support will remove it soon. But, to be honest, the data recorded by RS800CX is far more important, as it contains HR and speed (plus cadence and altitude and incorrect (body?) temperature). For this analyses I have used the standalone Polar ProTrainer 5 software. I'm quite disappointed that Polar has stopped developing it :(
So the data from the RS800CX. Unfortunately the speed from the footpod was inaccurate: at the end of session the watch told I had run 39.6 km's. So the speed and and paces in the analyses have correction factor 1.0655 applied.The toilet stop HR drop is nice and clear in the graph (stop length was 1:30, as the watch says)
You might remember from my previous blog post that I had five different sections during the race:
- For first 10 km (Actually 10 x 5:28 min) I tried to keep HR below 165
- After that, till ~14.5 km, I tried to keep it under 170
- Between 14.5 and 26km I was "chasing" the 3:45 tempo maker group
- After that I stayed in 3:45 group till 33/34 km
- Somewhere between 34 and 36 km I left the group behind me, and ran as fast as I could till the finish line
Lets look at the data for each section:
First 10 km
This was slow and boring. It has green arrow on chart, because it was "easy" part of the race. Perhaps I should have ran it a bit quicker. Or the part should have been quite shorter, like 30 min? I was thinking if I should take out the toilet stop, but- It did not change data much
- The stop was somewhat compensated by a bit quicker speed during next minutes.
- Time 0:54:32 (0:00-0:54)
- Heart Rate (Average/min/max) 163/103/170 bpm
- Pace (Average/min/max) 5:34/16:12/4:36 min/km
- Distance 9.48 km
Below 170 bpm
Yellow as it was hard enough. Perhaps it would have been correct effort for the most of the race.- Time 0:23:25 (0:54-1:18)
- Heart Rate (Average/min/max) 169/161/175 bpm
- Pace (Average/min/max) 5:04/11:01/4:11 min/km
- Distance 4.58 km
Chasing 3:45 group
That section was a bit too hard. It was relief when I reached 3:45 and had a chance to rest a little. So red is a good color for it.- Time 0:57:10 (1:18-2:15)
- Heart Rate (Average/min/max) 172/165/178 bpm
- Pace (Average/min/max) 4:55/9:13/4:09 min/km
- Distance 11.61 km
In the 3:45 group
Resting from previous harder effort, but still hard enough- Time 0:41:22 (2:19-3:00)
- Heart Rate (Average/min/max) 172/167/179 bpm
- Pace (Average/min/max) 5:27/13:24/4:15 min/km
- Distance 7.57 km
Final effort
A bit quicker than previous but slower than "chasing" section. the heart rate is even higher than in the chasing section. The increased HR is kind of expected for final race part as the body gets tired- Time 0:41:47 (3:10-3:42)
- Heart Rate (Average/min/max) 176/169/180 bpm
- Pace (Average/min/max) 5:12/9:13/4:03 min/km
- Distance 7.99 km
And now I'm really waiting for my next marathon run, so that I can compare numbers with this one. I hope the will start telling me more. Or, can any of readers help me? All comments are welcome.
