I'm back. I did very little running in the last 5 weeks, gained 3-4 pounds, and certainly lost some fitness, but this morning I went for an easy 5 miler, and I feel just fine. I'll build up with ~30 miles this week, then jump into 40 next week, and after that I take it slower with the 10% rule. Considering that I maxed out at 50 miles in the last cycle, I think my body should be able to handle it. Plus, I didn't entirely stop running in my break: I ran 15 miles on the week of 06/20 and 16 on the week on 06/27 (this latter was 4 + 12; the 12-miler was a great run from Veszprem through Balatonalmadi to Felsoors).
