Mighty duo and on the new bike! Much needed boost

Well I went for a spin on the new bike, planning to do a road session and then immediately a run, a bit longer than the first circuit of the village earlier in the week (and let's face it, you couldn't get any shorter) and glory be.... Didn't I end up doing around 20k and immediately followed by a 2.5miles run! Legs a total wobble own the run and did it at a snails pace but at least I got round. This provided a much needed boost for me during what has been a crap ..the only word to use here... Run up training plan for this tri. I don't feel like I have achieved anything but of course , I have achieved a bit. Can now do 2 consecutive front crawl lengths ,,might have to revert back to breast stroke but at least I am able to do that. The road session yesterday makes me realise I am ok with this bit and training on a heavy old bike should help me fly a bit faster in the day. Dinky danke as I usually say.  The run is surprisingly, the scary bit for me. Will I have anything left in the tank to finish the race and get me round the 7k? Not so sure now but still feeling better about the whole thing. At last.
