Subject: RE: IMLP bike coursemapmyride divides the elevation into about 75 little chunks. On a 56 mile course, each chunk is about 2/3 mile. And if it has 100 feet of climbing and 100 feet of descending in that mile, it will come out as 0% on the elevation chart. Similarly, if there is 300 feet of climbing over 3000 feet, it will show 10% grade, but won't show whether that's 1500' at 20% and 1500' that is flat or whether it's 3000 feet at 10%. Sometime between now and 7/25/2010, I'll go through mapmyride and divide it into much smaller chunks and record the grade for each in order, which will give a much more accurate profile. I'll post it here if anyone's interested. |
