I just returned from meeting with a branch in a village almost 4hours south of here. The branch is spread over a fairly large valley with several dependent groups in outlying areas. The missionaries bike 16 miles oneway to get to the area in hilly terrain ( like biking to Auberry every day) They have to start back 1.5 hours before dark because there is almost no electricity in the area. When they get back to the larger city, where their apartment is, they start working in another area. They are now biking 150 miles a week. They teach lessons wherever they go. 

At the branch meeting I met a family who walks 20 km one way faithfully to church every Sunday. I was overwhelmed when I learned that, and then I met a man who walks home from where he works 80 km (50 miles) each Saturday so that he can attend church on Sunday and then walks back on Monday. As I was sitting at the front of the congregation I was getting pretty choked-up thinking about that kind of devotion.
