I came back to running about two weeks after the West Highland Way Race, racing for a sub 24min at the Cambridge parkrun and then the next day took part in a 2.5km river swim. Looking back on Strava, I came back to training far too quickly, despite 2 weeks off running I had been road cycling over 100km just 1 week post race. Open water swimming 2 weeks out from such a large ultramarthon was a huge mistake. My immune system would have taken an absolute beating from the race. Both Max and I caught a bug from the river and were subsequently ill for 2 weeks, all training stopped and I was wiped out.
