I work at 8.5 km from home. I often take my bicycle (about 30-35 minutes), but when the weather itself looks like it would rain, I take the bus or get a lift from my parents.
The bus on the way home stops about halfway, 4 km from my home, which I can and have walked before. the path goes via a pretty busy road, but it has a sidewalk for about 90% of the way, and a cycling lane for the remaining 10%, and every busy intersection I need to cross has traffic lights. the road itself is mostly level, although the last KM has a slight decline. I've made a google maps that shows the path (not quite to my house, I'm not that stupid): https://www.google.be/maps/dir/51.1571561,4.4154346/51.146091,firstname.lastname@example.org,4.4352632,15z/data=!4m9!4m8!1m5!3m4!1m2!1d4.44544!2d51.15539!3s0x47c3f0982c5624f9:0x31820bda1d367bae!1m0!3e2?hl=en
My bus stops at the hospital. I can make a transfer there to a bus that follows the same trajectory, but depending on the time I arrive at the hospital, it's often just as fast to walk. However, I'm thinking jogging might even be a feasible alternative, given the relatively short distance and acceptable road conditions. What I'm wondering about is if I would need any special equipment or training to jog this part. Do I need special shoes and clothes or can I do this in my normal working clothes (button-down shirt, jeans or other comfortable pants, pretty casual shoes)? Would I need any particular training or excercise before I do this (I don't have an amazing or even great condition, but I can do multi hour bicycle rides of 40-50 km)? Is it sane to start with a 4 km jog right away or should I start with taking the bus and going from somewhere partway?
