I've got 4 weeks until my marathon, until just before Xmas everything was going to plan. Then I came down with this horrid cold that then turned into a chest infection. Anyhow, to cut a long story short. I've been managing to get out still, but my training has really suffered, i've not done and speedwork and i've struggled to get round my long runs.
The longest i've run so far is 15 miles. Any advice for how I should handle the last 4 weeks?
Thanks in advance.
