Quite possibly the hardest, most frustrating commute of my 6 years. Not only was it bitterly cold but, there was a constant, unrelenting headwind that kept tearing at my ears and pushing againts me, my chain squeeked mercelessly the whole way in and my legs completely abandoned me (stiff, tired, etc). I struggled, cursing all the way, againts these conditions. The bike felt slow and heavy, the hills were killing me, and there was absolutely no coasting or catching my breath at any point along the way. I also felt totally carb and calorie depleted. I felt like getting off the bike and tossing it into the woods, I barely made it in. I hope things are even slightly improved this afternoon.
