Ye old Sunday long run. Thankfully no where near as hot as last weeks Desford 10k. Did not really feel up for 10 today but as is often the case done better than thought. Couple of surprise sub 10s in the later miles as well. Nice. Wanted to keep a heart rate in the 150 to 160 range. Happy with that as well. Might be coincidence but have started kettlebelling again this week. Legs felt stronger, did not get the weak hip flexor feeling.
