All that matters is that Steve comes out of the winter period with an achievable target still in sight.
Bang on the mark.
I hope Steve stabilises his losses soon. The thing that catches my eye is that the losses are quite variable at the moment, ranging from 80 miles a day to 30 miles. Often with no clear weather-linked reason (particularly over the past week). That variability smacks of getting into a cycle of overcompensation following a disappointing mileage total.
In "similar" situations (chasing a record, albeit not one so hard) what I did was set a more manageable target when things weren't going to the master plan (in this case it would be "ride 10 miles more than yesterday") rather than attempting to push myself back onto the master plan (in this case, ride 205 miles).
Steve has the ability and scope to make up a reasonable shortfall come the end of winter, so a gradual clawing back towards daily Godwins is an option for him. Rather than pushing too hard too soon.
Of course, this assumes that the disappointing daily mileages being seen at the moment are due to his diet or some other physical limitation. Rather than simply fighting the weather (where a degree of variability would be more understandable). I don't know which it is, not being in Steve's inner circle. (In other words "what do I know").
