One True Grit - Nr Rushden A fantastically muddy obstacle course over 5k or 10k. We are one of the official charity partners for the toughest obstacle course in east Hertfordshire, One True Grit - designed to test your physical and mental grit to the max. Sign up as part of the Isabel Hospice Team and you get 15% off your entry fee. In April we had the biggest team entered, with 45 runners, and One True Grit kindly gave us £1,000 bonus! Let's beat that in October! Expect barbed wire, tunnels, ice, water, mud, 10 foot walls, scramble nets and hay bale climbs as part of a 5k or 10k course - the perfect event for teams and families as they require team work and camaraderie! To join the Isabel team, contact Megan on 01707 382500 or by email to receive the Isabel Hospice promotional code for when you sign up online on the One True Grit website.
