This was quite a journey. Just completed the marathon yesterday. Ultimately, old injuries were a lot more of a factor than I thought, and the goal changed from completing a sub 4hr marathon to just COMPLETING the marathon. It was pretty easy for the first 30km, then I hit the wall. Ended up with a 4:48 time, i’m extremely happy with the overall accomplishment.
The training was going for a 10km run about once a week, and then the rest of the time doing swimming, sports, etc, to not aggravate the knee injury.
This has helped me fall in love with cardio but not necessarily running. It was the cross training that I really enjoyed the most.
