I do a few shorter hard sessions in the next week or two and then focus on what unterhausen says, hopefully the shorter difficult rides provide a bit of a kickstart to things? If I were in this situation I'd also really try and optimize my time at controls, it's never something I've been very good at or had a lot of reason to change but given the small field of riders it should be a good one to try and maximize sleep time instead of shooting the breeze at the other controls.
