| As a 54-year-old runner living near Versailles, I would suggest to Mr Sarkozy that he tries running earlier in the day than 1pm if it is as hot as yesterday. At 8.30am it was already sufficiently warm to be becoming uncomfortable after 45 minutes.Peter Fox, Montigny-le-Bretonneux, France | |
| Interesting that Sarkozy is on a strict diet - that's not conducive to healthy running - I swear by a pre-run bowl of porridge with a little honey accompanied by a big glass of water.Kate, Bristol | |
| The best way to run everyday for many years without injuring oneself are: 1. Run at the pace you are comfortable with 2. In extreme or new weather, work out with right clothing and consume water before you feel thirsty 3. Increase speed or mileage only 10% over previous week - don't run 10 miles if you have done only 6 miles for many weeks 4. Stretch before and after run/jog for 10 minutes 5. Work out strength training 3 days a week to keep the quads, hamstring stronger which will avoid any knee, calf, ankle injuries 6. Don't run after heavy drink previous night 7. Check your shoes and change when worn out. use the shoe one size bigger than your size.Sridhar, Bangalore, India | |
