I am doing a charity ride, it is 75 miles a day for 2 days in a row. I do not ride hardly at all any more , and I need to start training.

I need to buy new tires for my old bike i am going to ride, right now i have 700 x 23 tires on the bike

what is a good size tire to ride for the longer distance and road conditons ?

also tire recomendations? cheaper the better, but i dont want to get a flat either.


also .... for training, how do you think I should train for this disitance? i know it isnt extreme or anthything , but i want to be prepared.



thanks !!
