Denture cleaning tablets work a treat for cleaning your water bottles on tour. Just pop one tablet in each bottle with warm water, let it soak for 15 minutes or so and then rinse thoroughly. Sparkling clean bottles!!
For the women, I really recommend the
Mooncup. Sure beats carrying a whole pack of monthly supplies along.
And we both second the advice to not get hung up on distances. We've met quite a few worn out cyclists over the last few months and most of them were just trying to do too much, upset with themselves that they didn't make a particular town on a particular day. Just relax and enjoy the ride, whether you do 10km or 100km a day.
