Mid run brain cramp

Still keeping to the plan. Ran my Esplanade 7.5 mile route today at 9:20 pace. This is the best pace I've had on an run greater than 4.5 miles...and it wasn't a hard run at all. I still freak out a bit during the 3-4.5 mile stretch. I start noticing aches and pains, questioning if I'm being too aggressive on the pace or distance, yadda yadda yadda. Once I hit 5, no pain, good pace, bounce in my step. I had negative splits from mile 4 all the way in. I'm going to have to get past this if I'm ever going to run a marathon. All in all, it was a good run.
Tomorrow's supposed to be a cross training day. I've yet to get off my ass on a Saturday. Might try a short trail run behind my house depending on how I feel.

Question: Anyone use a Garmin 405? Know someone who has? Had a casualty today, my HRM belt. Snapped the clasp before the run. I'm now suffering from data deprivation.

Nocturnal Runner

New 4.5 mile route (42:00) from the office to, and around, the common. I'm liking the downtown routes more than the southie routes. Feels a little safer. I can also work in more hills which has been sorely lacking in my other routes. The common is definitely an upgrade in "scenery."

Ankle is still a little sore, but didn't really bother my until the last 1.5 miles. Unfortunately, icing is a challenge in the office and will have to wait until tonight.

I've determined I'm a nocturnal runner. Yesterdays midday 1.5 mile run seemed much more strained than today's run. I just feel more relaxed and comfortable running pre-dawn. However, it was cool to see the sunrise again at the end of the run with the time change.

Question for those with HRMs. What is your average HR during a 4 mile/moderate run? What is your resting and max HR? Based on my calc's, my max HR should be 185. If I'm to believe the workout HR bands and what I should be targeting, I need to slow down. My average seems to always be around 165 with a max of 170 - 178. Just trying not to drop dead.
