You should add at least 1 full distance (21kms?) run per week soon if you are aiming for September.
Drop it down a notch the week before the race so you dont burn out though
I dont think you need to be running 21km once a week to be honest. You need a longer run (14-16km) but you still just need to make sure you are always feeling relatively fresh.
The first half marathon I ran was 5km further than I'd ever run before and I managed to do it in 100 minutes. The first one is always going to be a bit of a mental thing, but I know I went out really easily and finished very strongly, basically because I took a fair bit of time to make sure I would be able to finish the distance.
Before the most recent half marathon I ran I would've had one run in the few months leading up to it that went 24km, and a couple of others that went 19 or so. Otherwise I did alot around 10-14km and at a reasonable pace.
I'm somewhat fortunate that, as someone who is about 168cm and 62kg's, I have a body very much suited to longer distance running and particularly climbing hills. Short, strong legs and f**k all upper body. I might barely ever pick up but at least I can run!
To sum up, increase your long run a bit, but not to the point where it affects your ability to complete your other running. Before your first half up to about 16km should be fine. On the day hold back the first half of the race, ease yourself into it. Much better to go out too easy than to go out too hard. And remember running a long distance is largely mental, once you click into that mode of I'm going to run for x amount of time you can generally find your pace and stick to it. Well I find that anyway.
I might also be in the Sydney run, depending on how my soccer club is going. Was thinking of sutho to surf but have only just recovered from a knee injury so just taking it easy at present, playing soccer and just light running during the week, want to make sure it is right long term.
The first time i did a triathlon there was quite a steep hill near the end of the run. Lots of people walking up it. I was determined to keep running but was pissed off when all the walkers I passed ending up going passed me.
Dad does alot of tri's, but comes from the running background. His swim leg is average but he makes up a fair bit on the ride and then the run is the strongest leg at the end.
Dont think i'll ever be in them, however, terrible swimmer. I'm sure I'll end up on a roadbike one day however
