Where to for a camping weekend? around leicester

I UTFS and didnt get much out of it, am googling at the mo but thought i could try here as well,
my gf lives in leicester, and we want to go somewhere near and nice for a weekend camping and stuff, i'll go up on a friday night by train from london with my bike (can i even take my bike on a train from london? never tried) and we'd set off sat morning, not a long ride, maybe 20, 30, 40? miles to somewhere nice we can have a relaxed weekend away from the buzz and all the city nonsense. Riding back on Sunday afternoon, thought about Rutland Water anyone been there before? there are few campsites around,

would love to hear recommendations, also a good camping site enroute, would be great.
any advice appreciated,

thanks a lot

...can i even take my bike on a train from london?

I'm guessing you're using East Midlands trains, in which case yes.
Strictly speaking, they only carry 2 bikes per train and you should make a bike reservation (you'll need to show your tickets for this), however in practice extra bikes can be carried at the guard's discretion and I never knew anyone to be turned away in the time I was commuting between London and Sheffield.

i hear braunstone park is nice this time of year

@ Landslide: cheers for that, will make sure i check before
@ dicki: is this in leicester? i googled, and it is me thinks, ideally we're looking for somewhere to ride to and stay over.
also, we'll be doing the same around london, get a train somewhere out of the m25 and ride from there, suggestions accepted

Rutland Water has an amazing sight, Normanton Church: semi-submerged by the creation of the reservoir, with a path out and around it ... bonkers ...

Wooow, that's incredible.

It's mad. I went there aged about 10, and it's always stayed with me. The rocks weren;t there then, just a tiny concrete path around it.
