This is my first marathon but even so my times seem appalling compared to the ones here. Had my last long run today (Just over 20 miles) which is my longest yet and it did include a couple of big hill, including bear road but I struggled to a time of 3:45.
I did only have a small bottle of water for it but even so I am really thinking an extra 6 miles is gonna be hell.
Any advice for the next few weeks training and diet wise?
Are you doing any interval sessions training for a marathon is not all about long runs,what time you will achieve is all about how quickly you can run 200/400/800/1500mtrs most important that you have speed as well as endurance.Long runs should be about time on feet,i used to worry about pace when doing interval sessions and tempo and fartlek runs put effort into these sessions and your long runs will get quicker.
