Frequently Asked Questions

How do I cancel my entry? This is done yourself, via your account on https://www.sientries.co.uk/ . Once logged into your account, go to your MY ENTRIES / MEMBERSHIPS and you will see the Serpent Trail race entry. Click to EDIT MY ENTRY for this race and from there you can then follow the cancel place button to go through the process of cancelling your entry for the race.

Do I get a refund? Yes, this will be automatically processed to the card you used to pay for your entry once you have cancelled the entry. In the event of entry withdrawal there is a 75% refund up to 8 weeks before the race then 50% refund up to 4 weeks before the race, after which no refunds can be given.

Are there deferrals? No, due to the increased size of the event and the considerable time and planning that goes into it we have had to stop offering deferrals to the following year. This is because we need to be able to concentrate on planning for and providing the best event we can - this is our absolute focus in the lead up to the event. Over the last couple of years, handling the number of deferral requests in the last 2-3 months before the event has taken such a considerable amount of time to do the admin for, that we have had to change and set the refund policy as it is outlined above and fair for everyone wishing to cancel their place. The refund is now a higher amount (up to 8 weeks before the event) to make up for not being able to defer places.

Can I substitute my entry to someone else? No, for the same reasons as above; the workload of admin in the lead up to the event in dealing with requests such as this (and to defer) has got to a point that we have had to make some changes.


Do we need to have a waterproof jacket for the 50k if it is a hot sunny day? No. As the kit list states, you can have windproof OR a waterproof and if the forecast and conditions are fair then it is fine to choose just a windproof. Ponchos & Bin Bags do NOT qualify, so please don’t email us asking!

Do we need to carry a litre of water between each checkpoint? No. You must have 1 litre hydration system CAPACITY. Whether you choose to fill it up between each checkpoint is up to you. The weather conditions, time of day, fitness etc etc can affect how much you drink. Also as the race goes on you will probably want to drink more in the latter stages. Historically the race has been on a VERY hot day.

Will there be more checkpoints / water stations if it is a hot day? No. The support along the route is carefully planned and spaced out regularly to offer good support, plus being well stocked. There is ample food and drink in each checkpoint for you to take on with you and plenty to keep you going between support points.

Are there Toilet and wash facilities at the venue? Yes. The Rugby Club has good changing facilities which are open throughout the event weekend including through the night.

Are Dogs allowed? No. Unfortunately we don’t allow to dogs to run with you. They can however join you at the event venue and are ok camping and looked after by someone as you run. It goes without saying that you need to be responsible and pick up after them.

Can I run with a buggy / wheelchair? No. Unfortunately the Trail is not suitable for this.

I live near the start / I get travel sickness etc, can I register the night before (Friday registration) and meet the coaches at the start of the race, rather than using the event transport to the start? Yes - but only for the 100k and 10k races, and being there on time and in the correct place is YOUR responsibility! The 50k and 20k races have start locations on private land and DO NOT have space for extra cars so the coaches we are using to transport you will be the only way you can get to these race starts.

Are race numbers sent out in the post before the event? No. You collect them at registration.

Will there be vegan options in checkpoints? Yes. There will be a limited selection of vegan friendly options, though we recommend that for any specific dietary requirements you bring a reasonable amount of your own favoured nutrition.

I’m worried I won’t make the cut off’s, can I carry on if I miss a cut off? No. The cut off’s are designed to be achievable with good progress and should be achieved with a mix of walking and slow running throughout the race. The 100k is more challenging so if you are unsure then try the 50k distance first as this has a longer time limit.

What happens if I drop out or miss a cut off? We will transport you back to the race venue in one of our mini busses.

I’ve had enough and I want to drop out…now what? We will ONLY pick people up from the checkpoints. If you want to drop out then you can only do so at a checkpoint. (This of course isn’t the case if you have a medical emergency and need assistance elsewhere)

I have a Camper Van, can I camp? Yes, you can book your ‘pitch’ online and it is the same as a tent.

I’d like to camp but I haven’t booked online, can I still camp? Yes, you can ‘edit’ your entry via your Si Entries account and add it before online entries close, or sort it out at registration.

How do I get back to the Finish?* You run there. The venue is at Petersfield Rugby Club. This is where you come to the event before the race, park your car and register, then everyone is bussed out to the respective start points and you run back to the venue. *(true story, we have been emailed this…)

Do the races qualify for UTMB running stones? No - not running stones. The Serpent Trail 100k, 50k and 20k races are part of the UTMB Performance Index system (& ITRA) so they contribute towards your UTMB profile and performance ‘score’.
