Running from Mowbray to Salt River station again

For two weeks I have been working rather late. As a result of this, I was always trying to catch the 19:30 train at Salt River station, because the next one is a long wait. My work is in the suburb of Mowbray and there is the entire Observatory suburb between my work and Salt River station. Over time, I have been getting better in regards to running the entire trip. It is a lot of effort and the ground to run on is not smooth and it has some slopes.
