Great Job guys... metrics are very good goal, 100k is not bad at all. Over vacation I did two, one ended up about 105k with almost 45k or non stop climbing and the other about 120k mostly flat. (that is about 65 and about 75 miles or so). The first was a little over 3.5 hours and the second a little over 3.75 hours. An imperial century is a great goal... go for it...
