I'm taking a stab hoping for a reply or two from you trainers out there. I'm doing the Pfitz 18/55 and there is a 8-15K race scheduled for Saturday. I don't have access to a race, so I'm going to substitute a workout. I'm thinking I could do a solo time trial, but it sort of sucks keeping a race level effort for 6 miles all alone <img alt="sad.gif" src="http://files.kickrunners.com/smilies/sad.gif"><img alt="wink.gif" src="http://files.kickrunners.com/smilies/wink.gif">. Any opinions on running, say, (7-9) mile repeats with 30-90 seconds in between? Any other suggestions? Thanks!
