No reason you can’t get there. It’s not an out of reach objective. Keep at it and you’ll adapt.
Maybe you should pick a race to compete in to help you get motivated? It’s what I do with a couple of friends to make the goals real. There’s no slacking off when you know you have to complete something in the near future.
If you don’t race, no biggy. It does help with motivation when you have a goal set that has a fixed date, rather than a number like 4w/kg.
