Andy,

I know exactly what you mean. I was struck down by it two weeks before the Edinburgh Marathon in 2008 and in desperation I bought on of those velcro knee straps from Decathlon. Worked exactly the same for me too. It prevents the band snapping back and forth across the knee which causes all the tightness and irritation. That one pinged off somewhere around Mile 22 but it did the job and got me around pain free.

Touch wood, I haven't been troubled so far this year (doing loads of strange exercises plus some cycling) but I might pack one just in case.

Decided on the Friday the 13th of July :wink: as the new date, 6:30pm start. Want to be well clear of Wasdale before the rampaging hordes descend for the race on Saturday!
