I wouldn't recommend my lazysod style of training, but I hadn't run since Brussels Marathon last october, then ran 8 miles on 2nd Feb, then ran 12miles on the 13th, and today, 19th, ran 16 miles.. If I can run 23 next weekend, I will be well on target to pb for my Marathon at Dusseldorf on May8.
Be careful of those injuries though, and be prepared to step back. I'm just very lucky to be a neutral runner, with few if any injury niggles.
