brumrunner - Take care of the foot first, then you can worry about getting in solid training.
CTA - The difference between 10 @ 6:50 and 10 @ 6:56, during training is almost negligible, as there's plenty of factors that make up for those 6 seconds that are unlikely to play a part during the race. To answer you're question, I probably do 99.9% of my running alone. If I'm lucky enough to have company, it's only for an easy 6 miler or so. Personally I like training alone. It prevents me from going too hard on easy days, I can dictate my own paces for workouts, run on my schedule, and not feel bad if I need to skip a day. Plus, I don't know about you, but I always manage to find those gaps in races and inevitably end up racing solo as well. So in that respect, training solo has a huge benefit. That said, there are plenty of runs (mostly workouts) where having a group or at least one other person would help.
marmite - Looks like a busy week, and yeah, if you can string together more of the same, you'll be golden. Although, you've already strung together some fine work over the last couple months, so I'd say you have some breathing room.
dcrunner - Great looking race...and jeez, you closed pretty quick with that 2:29 last half mile!
themack - Same amount of miles in less days, good stuff! I can't say I envy those who have to worry about poor road conditions this time of year. Even this time of year, I have to worry about heat exhaustion long before I'll worry about hypothermia.
Numbersguy - Good workouts this week! I totally agree with you about sharing your progress with others...that's why I participate in this thread :)
Young Guy - Ho hum, just another week with an 8:41 3k. Kidding of course, but it looks like you've still got plenty of strength left over from your Vegas training cycle. Throw in some speed and you'll be ready for anything!
