How long does it take to get from London to Paris?

Question

Gonna be in London in November and we're thinking about making a day trip to Paris and doing a biking tour of the city.

Answer 1

45 mn by plane or 2h15 by train...the advantage with the train is that you dont spend 2 hours in check out and you leave from the center of London and arrive in the center of Paris ..

Answer 2

Are you flying, using the car or your bike or did you decide to walk there or maybe swim???

Be more specific.
