Solid run down on the Lowlands. Foggy as hell, HR monitor wasn't wet enough so didn't work properly. Ran in the Hyperspeeds which actually felt quite good with the Adios laces in them holding a bit tighter to the feet. Not sure if there is enough show there for a marathon (for me) wil be interesting to see how the calves pull up because they only have 6mm drop. They feel much firmer under foot and flatter. Didn't feel like I would have gotten blisters. Ran 8k at Half marathon pace hitting; 4:45, 4:33, 4:36, 4:32, 4:37, 4:35, 4:32 and 4:30. Legs felt pretty good, same old calf issue (post tib) and tiny bit of left shin tightness right at the end - something to be aware of.
