Please could you help...i was hopeing in take part in the 2011 event i have recenlty down loaded a 16 week training plan for running 100Km at the end of it. Could anyone tell me what KMs should i be running the week before i start training the program.Also the most i have ran is a full marathon in a time of 4.20 which i was doing around 65-70 km week leading up to the event would 12 months training be efficent for the 100km...Thanks for your time
