Can Someone Please Advise On This Great Value But "Impossible" Ticket Please?

[SailRail]

I have a cross-country journey to make tomorrow. I found great value on the ticket but the route is "impossible".

Here it is:

Leave Chester at 16:35.
Arrive London Euston at 18:39

Depart London Euston at 18:39
Arrive Kings Cross at 19:14

Leave Kings Cross at 19:14
Arrive Cambridge Station at 20:05

Leave Cambridge Station at 20:44
Arrive Newmarket at 21:03.

Now, I'm a relatively young man, and not completely unfit, but even I suspect getting from a mainline platform to a tube line (and vice versa) in precisely zero seconds might be pushing it a bit (especially for someone who hasn't been in a London station of any description for going on 15 years).

This ticket is being sold on Abellio Greater Anglia in good faith. However, it says the ticket is for the specific trains only. What is your advice on purchasing it? It is significantly cheaper than other options, but would I have a strong enough case when questioned by a ticket official if I said "yes, I'm aware this is not the correct train, but I simply couldn't make it from platform X to tubeline Y in zero seconds"?

National Rail planners often do this with tube journeys. But it's one stop on the Victoria Line, and can easily be done in that time.
In fact, you can walk from Euston to King's Cross in fifteen minutes.

Ah ok, thanks. Would it be easy to find my way given my lack of experience of London? If things are that close I usually walk in these situations, in my experience by the time you've walked to the platform, then waited for the train, then gone from the platform to where you're going, you'd generally have walked it twice in that time.

Yes, as you come out of Euston, just turn left and follow the main road until you get to Kings Cross. You can't really go wrong.

Great, thanks.

That bit isn't really a 'train service' timing, it's the all-in interchange time between Euston and Kings Cross. There's a whole table of them (at least for the more usual or obvious mainline interchanges), shown in the National Rail Timetable, I've attached a copy which should reassure you that the timings are legit:

The first station you get to will be St Pancras. Don't go in there, carry on over the next junction and you will see Kings Cross (big yellow brich archy thing).

...and as it's peak-ish time on a weekday, you might find it less hassle to walk it anyway instead of being a sardine on the Tube.

Don't worry about the London - Cambridge leg if the train into Euston is late, there are plenty of trains to Cambridge all evening, and the last connection onwards to Newmarket is at 22:44

I would generally walk between Euston and King's Cross rather than take the tube, unless it's raining heavily!

This is the walk route: http://goo.gl/maps/tDOWd

Thanks everyone.
