GPS data of the climb to the Ol Doinyo Lengai. The collection is spotty because the batteries were dead and we were turning it on for seconds at a time. The data was recorded on 2003-09-10 between 0:15:45 and 18:05:30. There are 26 data points recorded, 7 data points were less than 10m apart and were removed. The path length is 7.73Km, with a total climb of 1657.0 m. Altitudes are measured in metres, all other distances in kilometres. The speeds are averaged over the last minute or the closest approximation to it.
