I have just done a 12 mile run and felt a bit of stifness/soreness in the lower back in the last few miles. I have a reduced disc9L$ i think) and do have some issues. However it has never felt as it does now. I went to slouch (bad I know) on the sofa and the pain was really sharp I could not stay in that position, I am sat up properly as I type and it is not too bad. The sharp pain was jiust above the sacrum Any advice anyone?
Thanks everyone. Did the run today it was hard but I am sure it was a good session. YD you were right it was still VO2 max workout too. I had to do it in a lunch break so not enough time to take longer breaks and make it even more of a pure speed session.
Not sure Cliff quicker then my 1500m pace and probably with longer rests but not sure exactly how quick or how long. Maybe 400 or 800 pace with nie big breaks of say 5 minutes. Thats a guess though rather than any knowledge of how to train for a 1500.
