Hi,
The first requirement will be that you'll need a passion for writing and traveling
Practice your writing as much as possible so you can start building up your portfolio. You'll most likely be sending articles to travel magazines for publication.
Create your own Youtube channel like this: FunForLouis
I must tell you that its a great career option. You would be able to travel and work at the same time. Now coming to the point of approach.
1) Find out what are the future prospects of this job, you can easily get that from Google. Approximately how much would you earn?
2) Find current professionals from the industry on linkedin and ask them all your doubts. Generally, people do help out.
3) Are you comfortable with being away from the family most of the time? Try to find out the practical problems of this job.
What you can do:
Take up Mass Communication & Media Studies
Start freelancing for travel websites
Travel a lot yourself & keep yourself updated with all the happening places at least in your area or of your state.
Organize travel & tour operations, excursions, trips & picnics.
Read travel narratives and about travelers like Ibn Batuta, Marco Polo, Richard Hakluyt, etc
All the best!

Hi Shivam,
I believe people like Harsha Bhogle are extremely rare (i.e. people who haven't played the game at First Class level or higher) and it's getting increasingly unlikely that you'll have a shot at that role unless you play the game professionally first. There's more former players becoming commentators and experts and they are far more likely to get the positions you're applying for.
But if you want to be a studio host for a sports / cricket show, you may have some luck. You do need ample cricketing knowledge, quite a lot of charm and charisma and the ability to host which, to be quite frank, is something that is more innate even if you can hone your skills after that.
Star Sports has ample money to hire all the big names so you may want to start smaller. Even that will be unlikely but it's a better bet. You could start off with having a YouTube channel where you do quirky, off-beat, interesting cricket analyses / reports to get yourself noticed. Or work at a place like ESPNcricinfo, CricBuzz, Sportskeeda etc as a Journalist who can also do video. But you'll need good skills in all departments if you want to actually tour (camera-work, editing, audio, interviewing, carrying stuff around, producing, graphics, packaging.). That's what I do, but I don't really want to host in a studio and I don't think there's much of a chance of me sitting in the commentary box unless I'm called (after years of doing this) as a one-off semi-expert on something cricket-related.
If you're good at the starting steps and get noticed, you have a better chance of getting some of these one-off gigs and you can go ahead from there.
But my dampening word of advice on the matter is that you'd be better off trying to become a sports journalist or a roving reporter / presenter (like Gautam Bhimani or Gaurav Kapur) rather than trying to emulate Harsha Bhogle.
Also, learn to commentate in Hindi and English if you do want to work for Star. That'll help your case eventually.
All the best.
