Hi folks, During 2010-2011 and early 2012 I ran 3/4 times a week and completed half and even did 1 full marathon a mid paced runner. I then due to job change and losing my mojo I stopped running now march 2013 I have my mojo back and have entered Chester marathon October 2013. I know what sort of training I should be doing for the 16 weeks leading up to the marathon it's the how much and how soon to be doing miles pace etc now that I'm struggling with. I have ran 28 miles at a slowish 9.25 pace over the last 2 weeks and on today's run my calves are sore and hurting, Do you think this is because of too much to soon ?? Any advice would be much appreciated.
