Stats
Measurements All measurements were made with a Polar 625SX HRM fixed to the handlebar of the bike. Towns The towns listed are the the location from where I started on that day. The arrival town for a given day is the starting town for the following day. Distances Distances recorded on each day are the distances actually traveled and are in most cases more than what is quoted in the guides since they include small side-trips and riding around to find a place to stay. Leaving St. Jean Pied de Port I forgot to turn on the monitor so the distance recorded is less than what it really was. Average speed This is the average speed during the actual riding Times Quite selfexplanatory but just in case... Time riding is time actually pedaling, Total time is the time from the moment I got on the bike for the first time during the day until I got off for the last time that same day and Idle time is the difference between the two. Total ascent Differences in height are calculated by the Polar 625SX measuring differences in barometric pressure. The accuracy of this type of reading can be greatly affected by changes in temperature. Since the readings were taken over lapses lasting up to 10 hours, during which temperatures varied up to 34ºC there is bound to be quite a big error in the total ascents quoted. Regardless of above the accumulated ascent quoted in most guides seems to be much less than the actual climb - or maybe I was just very tired ;-) Calories The calories consumed will tell you little in absolute terms since for a given distance at a given speed the values depend on your weight, physical condition, efficiency, etc. Within some limits discussed in more detail on the calories page, what you can estimate from the numbers above is the relative differences between one day and another in terms of the work required to cover the stage. Temperatures Minimum and maximum temperatures were recorded on the HRM. The range is greater than what would be quoted by the weatherman because the conditions are not controlled. The minimum was usually recorded first thing in the morning in the shade or before the sun had come up and the maximum was some time during mid-afternoon when everything (including the HRM) had soaked up quite a bit of heat from being in the sun for a few hours. |
