Yes, biking 37km each way is pretty extreme. However, if you haven't already, I'd suggest questioning whether you should be making some changes in your life. Using rough calculations for a fairly efficient & economical car ($0.25CAD/km for gas, maintenance, and depreciation), your commute is costing you $18.50CAD/day (more if you drive an SUV/Truck)! That means if you could move closer to work so you could bike, you could pay an additional $350/mo in housing and still be ahead. Or, you could look for a new job that pays $4,600/year less net (probably ~$6,500/year gross) and be ahead. And if you could give up your car completely, those numbers could more than double!!
It's possible after reviewing the numbers, you'll conclude that it's not worth it to make any changes in your life, and that's fine! Work in agricultural and other rural industries is important. It's just that so many people aren't even ware how much their 20min commute costs them, let alone what it costs their local government (roads aren't cheap) or the environment in general.
