Are you going to add an auxilary power source, to keep your Garmin going? I'm starting to think your mental toughness, having a partner (to some extent), and 'bent all contribute to you being able turn such big miles on so few of training miles. I was averaging ~200mi per week, with a best of just over 400mi. I know there's no way I could do what you do, without someone for moral support, on a diamond frame. What you do/have done is truly an accomplishment.
