Recently a group working with the government has made an initiative that on Sunday from 4-7 they reserve a small part of the road for bike riders only.  I and my dad have been doing it consistently every Sunday. It’s definitely a good opportunity since with this initiative there are police who monitor the path, and will often direct traffic or let you know when/if you should cross. Usually, it’s a lot more brutal as cars take priority, and most paths can be very rickety, this Sunday leaves a day where I can bike with a feeling of safety. It’s nearly always on a flat road, with very few inclines either. From my house, the path is almost all the way to school and back. Its about 15 miles long, which is just shy of 24km.
