Hey Bidders, I was running near the front pretty and able to pretty much take the optimum line most of the time and I measured it 400m long on the 305. Someone else I know measured up 350m long. I believe it was long which is extremely poor.
I have a 305 and I made it 400m long, I measured on my OS map software and it also came out long. I've heard from another 305 user who also measured it as 350m long. Generally my experience of the Garmin is excellent. The discepency between measuring on my OS maps and the Garmin is generally no more than 50m so I believe that they got it wrong. I've also heard from some of the runners towards the front, who run very consistently and they are surprised their times are so slow. Like the experience of Louise it seemed to be the last three to four miles where it went wrong until then the mile markers where pinging along nicely at the same point as the Garmin. I accept that gps is not god but in my experience - which includes runing in heavy tree cover, running in town, running along the Portway and tow-path on the other side - it is never that far off. 50m yes - 400m no.
And also bear in mind that last year some of the mile markers where woeful, one mile, think it was six or seven took 9 minutes while the next took just 4.5 which doesn't really build confidence in Bristol ever getting things right. On a happy note, thought the start was better organised this year.
Hi krukers It's an Oregon Scientific Action Cam 2000 (also known as ATC 2000 or ATC 2K). Not the highest quality device to ever grace the planet but does the job and seeems fairly robust (comes with an array of mounts to mount on bike and helmet etc). It's barrel shaped, about 12cm long by 4.5cm diameter. Takes an SD card to store the video and two AA batteries. It produces mpeg4 avi files. Just connects to the PC by usb and shows as a removable disk. Editing wise any video editing sw will do. I use a cheapo program I downloaded from the web called 'AVS Video Editor'.
Hi Peaceman, It's bodged to the top of my baseball cap, forming the 'cap-cam'. It took me a few races to get the angle right though. My first film was mainly of feet and the ground with the odd glimpse of peoples butts. Then I over corrected and made one which was good for ornithologists, lovely views of the trees. Finally, after about six races, I've managed to get it to the point where it captures the race eye view.
