Getting There:
Crone Woods car park is the same car park as used for the Powerscourt Uphill race. It's at Grid Reference O 19126 14196 and 8km from Enniskerry. From Enniskerry head south following signs for Powerscourt Gardens and Powerscourt Waterfall. Pass the entrance to the Gardens and continue along a windy road for about 3km. Turn right at the T-junction, still following signs for Powerscourt Waterfall. After about 1km you pass the entrance to the waterfall. Continue along the main road for about another 2km and the entrance to Crone Woods is on your left.

Car Pooling: Not mandatory but strongly encouraged. With the addition of the Short Course this year we hope to have a few more doing these races, and Crone Woods car park can get full of walking groups, particularly at weekends/in good weather.

Organisers Instructions:
The first Nav Challenge of 2013 will be held starting from Crone Woods. The Nav Challenge is an open mountain navigation race, where competitors use a map to find checkpoints. As previously advised:
  • there will be an introductory Short Course aimed at anyone interested in learning navigation basics, distance about 8-10km (480m climb)
  • there's no kit requirement for the Short Course
  • maps will be provided for both Long and Short courses, no need to bring your own

Kit Requirements:
Short course:

  • no mandatory kit required other than what you'd bring for a Leinster League mountain race
  • that said, if you have a compass bring it along
Long Course:
  • Compass
  • rainproof jacket
Recommended (but optional) for both Short and Long course:
  • sufficient food & water
  • hat
  • mobile phone

Registration, Fee & IMRA membership:
You can register on the morning from 10am. Registration will close at 10:45am sharp with no exceptions. The cost is the standard €7 (€4 for 65+/unwaged). The €10 annual membership fee is being waived as there are very few races left this year. You don't have to have run an IMRA race before (but see below for 'Level of experience required').

Distance & Climb:
Short Course: 8 - 10km, with approximately 500m climb. Expected winning time about 60 minutes.
Long Course: 14 - 16km (as measured in straight lines on the map), with approximately 1000m climb. Expected winning time about 95 minutes.

Terrain & navigation:
Short Course: This will stay mostly on forest roads within Crone Woods, with possibly a small amount of open mountain on tracks. The navigation will be straightforward, mostly track junctions.
Long Course: This will be mostly across open, untracked mountain. checkpoints will not be hidden, but poor route choice or poor visibility may make navigation challenging.

Level of experience required:
Short Course: no specific experience required, ideally you've managed some of the Wednesday night Leinster League races or similar.
Long Course: some experience of navigation required, and physical ability to run the distance within the cut-off times (see below).

A specially-commissioned map has been produced by EastWest Mapping. Scale is 1:30,000 and as with all EastWest maps it shows an excellent level of terrain detail, with useful additional detail such as access points, parking etc. A full series of maps covering Wicklow and beyond is available from their website or outdoor shops, bookshops etc.

Early Starts and Cut-off times: Early starts are available on a self-timed basis for those that are typically 160% + of winning times in other IMRA races. If you would like to start before 10am please contact me (086 262 1445), otherwise let me know on the morning. A strict cut-off time of 3:30pm is being imposed. Competitors returning after that time will not be listed in the results. The cut-off is not to punish people, but to ensure that those who might take longer will start earlier, allowing the RD & Volunteers to finish at a reasonable time. The RD would strongly encourage you to start early if possible

Gareth Little is the mastermind behind Nav Challenge 1.

GPS units, groups and following:
GPS units of any description are allowed, but competitors with GPS units are not eligible to win (nor are they likely to). If people wish to take part as a group that's also no problem, but again will rule out eligibility of winning. Following another competitor blindly is not recommended, but impossible to monitor - do so at your own peril.

Prizegiving Location:
Old Forge Inn, Enniskerry (Food is available)

Volunteers (Non-Running)

You need to have done 2 non-running volunteer roles in a calendar year to qualify for end of year prize

Current Volunteers

Volunteers (Running)

Check with race director if they have a need for people volunteering and running. Race directors need a minimum number of people available throughout the race to make the race work so non-running volunteers are preferable. While it can be helpful, volunteering in a volunteer and race capacity does not count towards qualifying for end of year prize
