Steady 4 miles, eastville park, snuff mills, as walk on sunday then extra mile at the end.
HR low to ridiculous for first few km. then it spikes hugely & I go from zone 2 to zone 4. When I buy a chest strap, i will look into this, but it could be that my body doesn't like runs of longer than 30 mins....... oh dear.
