Well done to the pacers and sorry to hear of your fall Dan and the other pacer being sick. They are all runners and accidents and sickness and bad run days must also affect pacers.
I followed a pacer for the first time at Silverstone and he must have been slightly quicker as I lost him at 9 then paced myself and still came in under target.
So he got me to 9 when I realised he was a bit quicker I adjusted.
I can't imagine the pressure to get peeps round for a sub 3!
I was supporting yesterday and there were big gaps between pacers on the same time but I put that down to the start times and pens.
