The ipod has helped me when I'm training alone. I've been doing 90+ for most of the summer and probably 30-40 miles/week are with an ipod shuffle. At first, I was a little self-conscious about it but then something happened that made me loosen up:
I was cruising along doing probably my strongest tempo of the summer, not listening to music, shirtless, and feeling fairly badass, as we all do from time to time. After rolling by a couple of 13 year old girls, I heard a loud "eeew" and giggling.
That incident underscored the futility of worrying about my appearance--you just can't win. If a "real runner" sees me with an ipod and looks down at me, I'll let my pace do the talking.
A few other things that help me get through the long, lonely miles:
- Keeping the air conditioning cranked during the day.
- Doing my long run midweek (if feasible) so I don't lose my weekend. If I do 20 on Saturday, I have a hard time staying up past 9pm. A few drinks and some nightlife are an important respite from training for me so I try not to sacrifice that to the long run (although if it's a choice between beer and getting the run in AT ALL there's no question that I'll be running).
- Getting some ice baths. Lots of runners do it regularly when they have access to a college training room and then stop completely when they're doing high mileage over the summer. A quick soak in the tub (no need for ice, cold water is enough) can make your legs feel a lot better when you head out for a second run.
- Eat well and hydrate. Meat and dairy always seem to help me recover from hard training.
- Progression runs. Most of my summer runs are some form of progression runs. Other than the physiological benefits of this training, there are psychological benefits too. It's easier to get out the door when there's no pressure to start flying right away. It also makes the run more interesting because you have to pay very close attention to your body if you want to be gradually increasing the pace for an entire run. It always seems to make the run go by very quickly.
- Really try to find someone to run with. Even if there's nobody around who runs at your level, it's fine to throw some slower miles in there.
