Having completed the big road drive (Delhi - Jaisalmer- Jodhpur - Delhi in 4 days) on previous weekend, we were high on driving!
The distance from Delhi to Lucknow is approximately 500 km by road. The standard route is Delhi - Hapur - Moradabad - Rampur- Bareilly - Shahjahanpur- Sitapur - Lucknow. Another new route that is becoming popular is the Delhi - Kanpur - Lucknow route. Some of my friends tried this route few months back and said that it is fast as it's a 4 lane road but longer than the standard route by about 50 km. We decided to take the longer and the faster one.
