The Nike+ Human Race 10K

6.2 miles. Nike+ 10k race. 56:00. Early morning run. Still waking-up. Clearly dehydrated prior to start. Trying to get it done before temperature rises. Laps of Bendwood Park. Unfortunately Nike+ device needed calibrated. No obvious way to do that. Came in 1.5km short on Nike measurement. Garmin 405 measured it accurately. Had to pause for water 1.5 km to go. Tried to push to end. Really tough - and took all day to recover. Had sore side throughout run.
