Chasing Numbers presents an inclusive and flexible midweek run that caters to all levels, from beginners to seasoned athletes. This unique 7-hour Time Challenge takes place along the picturesque River Thames, offering runners the freedom to choose their distance based on personal goals or preferences. ### Event Overview The event is designed to be affordable and accessible for everyone, with entry fees kept low through various membership schemes that provide additional benefits such as guaranteed entry and exclusive mini-me medal pins. For members of UK Athletics affiliated clubs, a £2 discount applies further lowering the cost barrier. ### Course Details Runners will traverse approximately 60% tarmac or well-maintained paths along the River Thames, with the remaining sections consisting of grass trails that can become muddy during certain seasons. This diverse terrain offers a challenge for those seeking variety and an opportunity to test their skills on both road and trail. The course is clearly marked, making navigation straightforward even for first-time participants. The flexibility extends beyond just distance choices; runners have multiple start times available from 7:30 AM until 3:30 PM, ensuring everyone can find a slot that suits them best. ### Distances Participants can run as little as 3 kilometers or push themselves to complete an ultra-distance of over 56 km. The standard lap distance is either 4.37 miles (7km) or may be adjusted based on course conditions and safety reviews conducted near the event date. This flexibility allows runners to set personal goals, whether it's a half marathon in three laps or tackling longer distances. ### Incentives & Rewards All finishers who complete at least 3 kilometers will receive an official medal as recognition of their accomplishment. For those aiming higher, distance pins are available for achieving milestones like the Half-Marathon (21km), Mega-Half (42km), Marathon (56km), and Ultra distances. ### Venue & Facilities The event takes place near The Last Hop in Staines, offering a scenic backdrop with toilets readily accessible. While there aren't separate changing facilities or showers provided, runners can make use of the spacious downstairs restroom for quick changes if needed. Parking is available at Bridge Street Car Park (TW18 4TP), and bags may be left securely near the start/finish area though valuables should not be left unattended due to limited supervision. ### Additional Information Participants are encouraged to stay considerate towards other path users while enjoying their run. Headphones can be used, but runners must remain aware of their surroundings at all times for safety and courtesy reasons. Final race day instructions will be emailed out a week before the event, covering everything from number pick-up procedures to detailed course maps and any last-minute updates on conditions or changes. Join Chasing Numbers this midweek for an experience that combines scenic beauty with flexibility and inclusivity, tailored perfectly for runners of all abilities.
