    • Did the 50km in 2019

      On Saturday March 2nd, I completed my first Lark Hill Dusk to Dawn night trail ultra. This took place on a 3K slightly undulating loop of mainly limestone track with some portions of sand. 25, 50 and 100K distances were on offer and I chose to run the 50K (17 laps). The event started at sunset and I didnt finish until well after midnight. As it was a loop, I didnt need to carry hydration- just a head torch.This is a good event for those wishing to extend themselves. Running in the dark may not be as scenic as a daylight run, but completing it in loops keeps one relatively safe by providing regular opportunities to seek assistance if needed. Moreover, the temperature at night is much more comfortable at this time of year. . It was very welcoming to see spectators and support crew each time you come past the start line. I salute all those who took part (in whatever capacity); especially the organisers and those who attempted the 100K. I look forward to returning next year.

      This was my first 50km Ultra, I found the course to be mentally challenging. In some ways it was great as you new what was coming but others parts quite a struggle as again you new what was coming.The event was very well run as the course is a 3km loop it easy to find your way as there is always someone In front.There is plenty of room for support crew and areas to leave supplies so you don't really need to carry a pack unless you want to. The organiser had plenty of water, there was also lollies and coke for those who use it.Over all I had a great time for my first 50km run and if work allows I will definitely do it again next year with a better preparation and hope to do it sub 5 hours

      Ive wanted to do this run for a while and I originally signed up for the 50. I had a cold so decided to do 25 but luckily David gently advised me to be sure and to not have any regrets! After the first few laps I felt great but I hit a slump at 25 kms and it was so tempting to stop. However Davids words rang in my head and I knew I would regret it if I stopped! So I kept Gotland damn happy I did . I needed to do a bit extra at the end but David came with me which was gold . The atmosphere was fantastic and the cheers and encouragement as I passed the crowd with each lap was fantastic!! The only thing I would change woobevto have a flask of hot tea to drink and some dried fruit and nuts to nibble on in the wee hours. I loved the course apart from the sand - but thats my only whinge . Next time I will take a swag and stay the night and be there for the 100 km runners . Just loved it - thank you

      This race starts shortly after a spectacular sunset, viewed from the start/finish/aid hill. The limestone path is quite wide and very stable underfoot with only a few sandy/dusty edges. There's a short sandy fire-track section, which makes you change your gait, a relief for tired legs! The course has minor undulations and is clockwise through coastal vegetation. The start/finish/aid hill has an iconic rustic shed and windmill. The aid station is DIY, which for me was an cool box full of all kinds of food and drink, but the race director does provide some essential supplies. For me this was a great opportunity to test nutrition strategies and night running. The atmosphere is incredibly relaxed and supportive.
