I know it's not all about the winning, but that's a rather low level, and fails to take into account the cumulative effect of racking up some miles and the lack of opportunity to increase the score by doing locks etc. Imagine I was able to do 25 miles on day 1 and 15 miles on day 2. I think most people would agree that would be a fairly substantial undertaking, yet it would score a measly 60 points. In fact I would bet that it would be nigh on impossible for a walker to even finish in the top half of the table. If participation of other groups is desired, I doubt 1.5 points per mile with no bonus sections (for disused canals for example) is likely to achieve that.
2.5 points per mile for disused sections would be an idea.
And what about bonus points for helping boat crews if they get stuck or something like that? Or bonus points for collecting litter? I'll be honest, I'm not sure how any of that would work in practice!!
I assume walkers can still score points for solving clues and taking the required photos? Although I'm not sure how that works when the scores are based on boat length?
Of course, Sue and Richard are a very clever pair, so I'm sure they've got this all in hand.
If I do it, I'll probably take the BCN Challenge twitter account out of retirement as it's been quite a useful way of keeping abreast of all the excitement as it unfolds.
