Very little running done at my end. Away with work all day Wednesday, didn't get back until late tast night so could only manage 6 miles. Too icy to risk a 5 miler this morning and I'm on a boys weekend now so will see how I feel Sunday evening.
Back on the plan from Monday.
Sounds like you have a decent level of ability and background. It will all depend on how training goes. I'd agree with all the above. Just focus on keeping those consistent 40 mile weeks going and then see where you are in March. A half towards the middle or the end will be a decent indicator.
