If I was you I would split the runs up throughout the day rather than running 25 plus miles in one go. Maybe get up and crack out a gentle 6 miles, have some breakfast and a coffee, crack out another slow 6 miles and then have another coffee and a cake whilst you read the papers. Then crack out another 6 miles and stop for a long lunch break and then plod on for another 6 miles before going for a massage.
If you have second thoughts and are ok to pay the hotel, massage and lunch bills I will step in for you as it sounds better than my usual week at work.
Obviously it will get harder each day and after 3 days you will probably want to cry. Anyway good luck.
