One of the things you will discover is that when you friends, family, and cow orkers will be stunned to discover that you are riding 13 miles a day and will feel concerned that you may not be safe, worry that you have suffered from an economic downturn or a dui, and will offer to give you rides.
A few people will see you doing this and find inspiration and might just try it themselves.
Keep this up and that 13 mile ride will start to feel like a warm up and you might find yourself looking to ride longer and farther and people will be more amazed.
My long commute is 60 miles a day... it is often the best 4 hours of my day as much of it takes me through the countryside and I do look forward to seeing the city vanish into the distance behind me when I head out.
Sometimes I take the long way home and can turn my 100 km day into a 140 or 160 km day.
