When should I start training for the London Vitality Half?
For a May race, start a 12-week plan in mid-February. UK February weather varies widely — build your training around what's available and don't skip sessions due to cold or rain. Consistent training in imperfect conditions builds mental toughness that pays off on race day.
What is the London Vitality Half course like?
The course runs through central London, past Tower Bridge and along the Thames Embankment. It's largely flat with a few gentle rises. Road surfaces are good and the crowd support is strong throughout. Logistics at the start (transport, bag drop) can take longer than expected — allow extra time.
What should I wear for a May half marathon in London?
May in London averages 12–18°C (54–64°F). A short-sleeve technical top is usually sufficient. Check the forecast 48 hours before and have a thin long-sleeve option if temperatures are below 10°C at the start. Avoid cotton — it holds sweat and causes chafing over 21 km.
How do I get from my training in km to miles for a UK race?
PaceForm lets you switch between km and miles — all your training zones can be displayed in either unit. UK road races are measured in kilometres but pace displays on most UK GPS watches default to miles. Set your watch to km for consistency with the race distance markers.
