clubber
im 17.5 stone and as unfit as they come!!!
i did whites level in the morning and was tired after doing so.
we came back to the drop off cafe and had some lucnh by the tent to rest a bit and then we set off to do w2 in the afternoon.
yes i was a lot slower going up that bloody climb the second time round(even fell off and rolled down the hill a bit due to fatigue ) but after the climb its mostly xc trails .
ill admit i was very VERY tired by the time i got back and didnt feel like riding the day after.
to the OP i would recommend doing just the w2 trail as it takes in the whites level stuff anyway.
cheers
