Colchester Half Marathon
Colchester Half Marathon is a rolling half marathon in Colchester, UK, held each March. A single-lap road course from the JobServe Community Stadium through the city centre past the castle, then out onto rural lanes. Listings call it undulating, with several climbs in the countryside half. Early spring in Essex is usually cool and fairly dry, around 3 to 11°C. With Colchester Half Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
