I have been carrying my Fitbit One for a little over two years with me and it keeps tracking my daily steps. It also tracks my distance covered by multiplying those steps using the stride length which you can either provide explicitly or implicitly setting your heights. In the winter of 2012 I bought my first ~Garmin Forerunner 410~ (replaced by a Garmin Forerunner 920XT) GPS watch to help me track my running (and other outdoor) activities.
I have been tracking my sleep for almost two years now using my Fitbit. I started with the Fitbit Ultra and then moved on the the Fitbit One after it came out. In October 2013 I found out about the Sleep Cycle (Link) app for the iPhone. For weeks, Sleep Cycle was listed as the best-selling health app in Germany, where currently (as of January 2014) it is in second place.
After the 2013 Berlin Marathon sold out in less than four hours, the organizers decided to alter the registration process for 2014. First there was a pre-registration phase followed by a random selection from the pool of registrants to receive a spot. Those who were selected had to register until November 11th, 2013. Any spots that were not confirmed till the 11th would be offered to pre-registered candidates according to the order in which they were randomly selected.
After I moved back from New Jersey in June 2008 I started to track my body weight more seriously. My routine usually consists of getting up and after finishing the morning bathroom I would step on my scale. That way I try to ensure that the condition for each weighing are as similar as possible. I recorded my weight on paper and eventually would put everything into a spreadsheet for further analysis.
Recently I ran the St. Pat’s 10 Miler in Atlantic City, Nj. It was my first official running event ever and I enjoyed it lot. Shortly after the race the official results have been posted on the Internet. The data did not only include the number and times of the participants but also gender and age. Looking at the finisher time distribution it shows that most runners finished at around 90 minutes:
