I've taken the last 2 weeks completely off (1 run) after the OMM. I was planning on 2 easy weeks but mangled feet meant I took a proper rest. I'm now going to do 2 easy weeks (35miles or so?), introducing some steadier sessions to get back into it. Currently feel pants running for 30-50mins atm but hoping the rest will pay off in Feb/March!
Then 2 more weeks at normal tick-over mileage (~50) before trying to up my mileage compared to last year in an attempt to keep a roughly upward curve going!
Last winter I went from the OMM straight into XC with no rest. Sucked in November and couldn't work out why - dur! Got going well in Jan/early Feb before a March crash. I then unexpectedly pulled off my best ever performance at the end of March and that confidence carried me through the season at a similar level.
