Not downgrading

stats of  the week: run 13 km, cycled 97 km, hiked 7 km
stats of the previous week: run 34 km, gym 3 h (Berlin half 2:03:40)

The Berlin Half didn't show the result I hoped for. And I think it's not just the heat and Sahara sand I can blame. Legs felt tired from the first step on. It was a race with great atmosphere but I was not able to enjoy it. Already after 17 km I had to walk short parts. A bad day in good weather.

I am not sure about the lesson for London. Was it just a bad day or do I suffer from too many races during spring? I refuse to downgrade my target of a 4:30 finish on the mall. We'll see.
