Hi there thanks for the kind words from you guys, it is an honour for me to be able to help out where I can, I have made quite a few mistakes over the years, but as Einstein is quoted as saying “if you do not make mistakes you are not trying new things”, in regards to GPS I am a bit of a Luddite, I am not a technology guy, although I have been in programs where they have been used very heavily, they are a useful treacking tool for calculating distance and intensity, they work very well in conditioning games, do they justify the expense, well probably not for me to say, they are worth a look and a trial, I tend to use the practiced eyes of my coaches to give me feedback, so I tend more towards the subjective than the objective in that regard, it is really a see for yourself situation, cheers, ashley
