Slow 12k today. Felt fine until about km 7 or 8, then it was more work to get home. I should learn to eat and drink better during the run since takes more than one hour.
Only three weekends, four weeks, until the planned half-marathon. I'll try to do 14k next week, then 16k two weeks before the event, but then probably ease off the week before the half-marathon, which is 21097.5 m long.
