PEDAL pushers: City workers take a break from the markets to take part in a group spinning class in Canary Wharf’s Montgomery Square in aid of armed forces charity Help For Heroes. More than 800 people took part in the outdoor classes over the course of the day, which was organised by healthcare provider Nuffield Health. There was nowhere to hide, as every participant’s heart rate and effort was tracked through electronic belts and projected onto a live screen.
