Apologies if anyone else has posted this already but you can get a Garmin FR10 & a SIS Endurance pack for £79.80 on Sports Pursuit website today & for the next 10 days. Bargain! I bought the FR10 a while back & for the person who just wants a basic GPS watch that shows time, distance & pace etc it can't be beaten. You can get the Black/Red or Green Ladies version. Also, having used a Garmin 205, it's a fair bit less chunky, the ladies version is even smaller.
Check out dcrainmaker on the web, he liked it, I do too!
Another Andy here with the same problem. I had problems with my right ankle due to a football injury, which resulted in my right leg bowing slightly. This caused me to have knee and hip joint problems, as well as a permanently tight right calf muscle. I also got a grade 2 hamstring tear in my right leg. Whilst being seen by a physio for that, she noted that my right leg is shorter than the left, which was probably the cause of all my right sided problems. I bought flat 2mm sorbothane insoles on ebay & put one under my running shoe insole on the right foot only, you can get 4mm ones but I think 2mm is the most I could use and still get my foot in the shoe unfortunately! It definitely helps but you're better off going to a bio-mechaniscal assessor who can advise on custom orthoses.
After doing it twice for charities in 1990& 94, I thought I'd finally do another now I'm so much older I can't remember how bad I felt afterwards. I've been turned down four times in a row now despite being in the ballot of 160,000 for supposedly 40,000 places, so bugger 'em I don't think I'll bother anymore. It used to be the people's race, now it''s the race for people's (charities) cash. Going up to watch though, the atmosphere is still great, I'll have a few jealous moments but I'll get over them.
I've been to Tignes loads of times, (the last over 10 years ago BC - before children) you could run between the villages for a reasonably flat route, only trouble is possible traffic problems. The high altitude would make it tougher but all top athletes go altitude training so it's gotta be good for you! One other point, I vaguely remember seeing a gym with people running on treadmills in the end village, the one below the Grand Motte Glacier - if it's still there you could possibly get temporary membership or pay as you go. I thought they were mad, skiing all day was enough for me!
