My tentative route from Kanyakumari to Kashmir would be
Bangalore to Kanyakumari – Train
Kanyakumari – Trivandrum – Kochi – NH 47 – 307km
From Kochi reach Edapalli – 15km
Edapalli – Kozhikode – Mangalore – Goa – Panvel – Mumbai – NH 17
Kanyakumari to Mumbai – Approx distance – 1600km – Beauty of Konkan could be explored on this route
Mumbai to Ahmedabad – NH 8 – 545km
Ahmedabad – Samakhiali – NH 8A – Approx 300km
Samakhiali – Pathankot – NH15 – 1527km – Via Thar Desert
Pathankot – Hatli – (leave NH 20) – Dharamsala – Yol – Palampur (Rejoin NH 20) - Mandi – Kullu – Manali – (via NH 21) – 400 km
Manali – Khardungla – 510km
In all around – 1600 + 545 + 300 + 1527 + 400+ 510 = 4882 from Kanyakumari to Khardung La by bike
Khardung La to Delhi by bike – 1100km
Other than this I also need to consider the train distance from Bangalore to Kanyakumari and Delhi to Bangalore
Manali to Khardung La breakup
Manali – Keylong – 130
Keylong – Jispa Camp – 25
Jispa Camp – Sarchu – 84
Sarchu – Pang Camp – 77
Pang Camp – Upshi – 127
Upshi – Leh – 47
Leh – Khardung La – 20
The appalling distance will take me at least 2 months to cover… I may hv to find a less interesting and shorter route…

My first visit to Mumbai was in 2001 for an industrial tour in the final year of my degree. Second was for a connecting flight to Switzerland during my Germany trip. This is my third but real visit to Mumbai.I went to Andheri West with my colleague. Had breakfast and reached Andheri West Railway station… The crowd shocked me. I took a ticket to Thane.
