Thanks P2P! I think I have come this far now that I can't give it up. Once I've reached 1,000 km it will definitely feel like I've broken the back of it! I'll fetch the foam roller out and put it to work! Legs up a wall is something I'll try to master as well, my hamstrings are terribly tight!
What other foods would you recommend that are high in K and Mg?
Of course the usual go-to's for potassium are bananas and potatoes, which are great, but nuts and seeds like pumpkin seeds, sesame, flax and almonds are good sources of both nutrients. Leafy greens, beans and cocoa are also great to add. Maybe add some spinach to your cheesy toast. ;) I also love my Medjool dates. They are a good source of magnesium as well as good quick energy for a run on the go or in a trail mix on a hike.
Ok, well, I have bananas, 'taters, leafy greens, beans and nuts regularly so that's good. Will add spinach to that list as well. Funnily enough, my muscles are generally OK and can continue the next day for a few days in a row but think I'll work on the flexibility side of things with the "legs up the wall" and start laying in to the foam roller - thanks for the help!
