Any time you can ride more than you did the month / year before is a good thing.
Wrapped up July with a little more than 1000 km which included a number of metrics, a century, a little bit of mountain biking, and did not let a day pass without riding at least 20km... and it has been a long time since I have done that or been able to do that.
Took it easy today and only rode 20km but will be starting August by riding a century tomorrow.
The ride is actually a metric (105km) but since I will be riding to and from the start point I will add 45 km to my ride and it won't be hard to ride another 13km.
