South Cheshire 20 (Cheshire, May 10)
The South Cheshire 20 is a tough test of your physical and mental capabilities and boasts one of the UK's hilliest road courses. This year's race falls three weeks before the Edinburgh Marathon – so take it slow for a perfect last training run before taper if you're gearing up for a spring marathon.
Among a small field, you'll tackle 20 miles along quiet country roads through the pretty villages of Weston, Englesea Brook, Betley, Wrinehill, Shraley Brook, Audley and Barthomley.
If even the beautiful rural Cheshire scenery isn't enough to keep you smiling, you’ll love the legendary support from a friendly field of around 100 other runners, plus solid encouragement from the race's army of marshals.

Heroes Run 10K (East Sussex, May 17)
If you've been inspired by Flora London Marathon runners sweating in costumes from Batman to Baywatch, get a taster of fancy dress running with 6.2 miles rather than 26.2. Held in honour of 'the heroic', the Heroes Run 10K welcomes costumed heroes from the obvious (Superman) to non-comic book heroes like Nelson Mandela or Paula Radcliffe – or pick an unsung hero close to your heart.
With a flat out-and-back road course along Brighton's seafront and promenade, the race has surprising PB potential. But if you’re hampered by a bulky costume, it’s probably more fun to just enjoy the buzzy atmosphere from the friendly and fun-loving field.
As well as a memento and goody bag, you might also bag yourself a spot in the record books as the Heroes Run 10K organisers aim to set a new Guinness World Record for the biggest group of superheroes together at one time.

Ramsbury Circuit 5 (Wiltshire, May 17)
Spend your Sunday morning enjoying a scenic loop through country lanes and footpaths in the Ramsbury Circuit 5's stunning West Country setting.
This not-quite-five-mile off-road course comes complete with a smattering of mud thrown in and just one challenging hill. After a deceptively flat first few miles, the route's only hill pops up to surprise runners at the three-mile mark of this rural course through the pretty Wiltshire village of Ramsbury.
After this test, runners will be glad to find themselves at the final mile, which is downhill all the way to the finish.
Post-race, runners will find themselves at the centre of a village fete, with barbeque, tea and cakes, a free kids' fun run and entertainment including a brass band and a bouncy castle to keep younger spectators entertained.
Raby Castle 10K (County Durham, May 24)
Not many races take place in the shadow of a 14th-century castle once owned by King Cnut. Boasting hundreds of years of accumulated turrets, towers and history, entrants for the Raby Castle 10K cannot fail to be impressed by the stunning backdrop.
Nestled in quiet County Durham countryside, you can look forward to joining a wide range of runners for two laps on the tranquil paths of the private estate, with a few woodland sections thrown in to keep you on your toes.
The reward waiting for runners at the top of the tough-but-manageable climbs is a panorama of beautiful views of the historic castle and its rolling grounds.
Afterwards, take the opportunity to explore the bits of the grounds and castle you missed while whizzing round the race.

Saab Salomon Turbo X - Surrey Hill (Berkshire, May 31)
Ten miles (or maybe a cheeky bit more…) of what the organisers bill as "the ultimate trail challenge" – get ready for tough trails, lashings of mud and much more. This fast-growing trail series has races all over the UK with hundreds of hardy runners lining up eagerly at the start of each one.
The most extreme course in the series, this race is tucked away in wild woodlands. Be prepared to pull yourself up hills, tumble down the other side and wade through bogs, water, sand, marsh and other muck, including the extra-tough challenge of the Turbo X Zone.
Brilliant goody bags will spoil tired runners rotten, so don't worry about a change of shirt after battling through the bogs – you’ll be treated to a new technical tee worth £22 at the finish.
