Nearly all ELR members take part in races or timed runs. The parkruns at Wanstead Flats, Valentines Park and elsewhere in East London are informal and social runs to kickstart the weekend. In Summer, the Elvis series brings together local clubs in friendly competition. In Winter, the Sunday League and Chingford League are competitive cross country series. The London Marathon is one of the highlights of the year. Other key events are the Orion 15, Benfleet 15 and Essex Way relay.
