In this case, you can definitely save time by riding faster on rural roads. On city roads, keep it easy so you'll have fresh legs when you hit the open roads where speed matters more.
Indeed, training and in addition, fueling and hydration. The faster you ride, the more you need to eat and drink to aid recovery and get to your destination / work feeling fresh and energized as opposed to feeling worn down and fatigued - not a good thing if you have to work.
