I have an 8K to run on 3/29, and currently am not capable of running three miles straight. So, perhaps I'm in need of some help :)
Hal Higdon offers an 8K Training Schedule for the novice, intermediate and advanced. At this point I think I am a "novice", considering that I haven't run in I-can't-remember-how-long. The schedule is for 8 weeks, which would mean I need to start on February 2nd. There is one really good thing about this schedule ... it starts on Monday, 2/2 with no running. Ok, I think I can handle that.
Here is week 1
Monday: stretching & strengthening
Tuesday: 2 miles
Wednesday: 30 minutes cross training
Thursday: 2 miles and stretching & strengthening
Saturday: 30 minutes cross training
Sunday: 2 miles (this will be the long run day, but starts at 2!)
During the 5K, I did a run/walk but didn't really have trouble until mile 3. For sure I couldnt have run any of the miles completely, but I'm pretty confident I can handle a couple of 2 mile runs. Well, I hope so at least.
