I feel sorry for Kurt, but I think he could help Steve to get to a bigger distance than he otherwise would. One which may not leave much left to go for to get the 100,000 mile record.
We all know that long distance cycling is a mental thing rather than a physical thing. Steve has thought about this for 25 years. There's no way he is not going to give it all he has to get the record. And we all know that he is capable of riding very long days, for many days in succession.
If Kurt's strategy is to try and ride a couple of miles more than Steve every day, as the weather here improves, he is going to find that it will start to get very big on him. We know that Steve will ride very long hours in the spring and summer, and will continue to do so into the autumn. Kurt is going to have to ride longer days to stay ahead. But, as he does that, his average speed is going to come tumbling down, so he won't just have to ride a bit longer, it will be a lot longer. Then, one day, he won't be able to beat Steve's mileage. He'll give it a big shove the next day, and get back, maybe using his recombent. But Steve will keep on grinding, and it will happen again. And then Kurt won't be able to respond. Then Kurt will be in very difficult place psychologically and may well have to give up.
That's how I see it playing out. Of course, I don't know anything at all about Kurt. If he is able to match Steve when he starts cranking out the 20-hour days, 24-hour days or even 36-hour days, as he may well do in the Summer, then he will truly have earned his record. But I fear that Kurt cannot quite know what is going to hit him!
