Running Route

The map below shows the complete 21K running track around the Cholavaram Lake, finalized for CTM 2015. This 21K loop includes a wide variety of terrain, resulting in a more enjoyable running experience for the runners.  HM (21K) runners will complete a single loop, FM (42K) /Ultra (50K) runners will run the loop twice and Ultra runners will add another 4K linear stretch (U-turn) on top of the dam. The running route will be marked with white paint along the trail. Mile markers and direction markers will be placed along the route. 
Aid/refreshment stations are deployed at approx. every 2K (+/- 500m) and you will be crossing 10 aid stations along the entire 21K loop. Start and finish are at the GOJAN college campus grounds. 

Familiarize yourself with this route:

Terrain & Trail

The 21K running route is a multi-terrain marvel - the runner will pass across dams, through cashew farms, inside canyons, through paddy-fields, small villages, sand trails through dry river beds and across vast grass lands. The trail is a mix of hard dirt track, red soil with small gravel, sand trails, a bit of tar road and grass land. It is slightly uneven in some places and there is a small elevation drop/gain in several sections. Running on an uneven trail requires more presence of mind from the runner (especially FM/Ultra runners in the dark) to stay balanced. Do not venture off the trail into any surrounding water bodies or greenery. Barefoot running is not recommended as there is a 2K stretch with hard gravel near the canyons. (Refer picture below)

Hard Gravels:

Maintaining Cleanliness:

Runners are advised not to throw any cups, wrappers (chocolate/gels), other waste either on the trail or inside water bodies. Use the waste bins kept near the refreshment points. Cholavaram tank is one of the well maintained tank and major supplier of drinking water to the people of Chennai city. Therefore, requesting the co-operation from the runners to maintain the cleanliness of the tank and the trail.

Trail Tips
a.     The terrain is not same:
We call it as the multi terrain marvel. Therefore, running in the trail has its own unique challenges and be watchful and alert while running on the trail. 

b.    Find your rhythm:
Running off road can be exhausting, focus on finding the rhythm until you sense of being one with the terrain. 
c.     Run with a buddy:
If you are not aiming at a podium finish or personal best, run with a buddy so that you can be safe inside the trails.
d.    Keep your eyes on the trail:
It can be tempting to look at the nature around you, but doing so can quickly lead to tripping and falling it is advisable to keep your eyes on the trail. 
e.     Taste the Chennai Canyons:
It is best to avoid comparing your pace, as you will be slower than your normal road-running pace. Instead, slow your pace and develop a trail tempo.
f.      Sport with your Trail shoes:
If you have a pair of trail running shoes sport with them. They reduces the chance of ankle rolls with a high heel. 
g.    Accessorize.
It is advisable to apply sunscreen, wear your sunglasses, cap/hat or carry a piece of white cotton cloth to cover yourself when the sun is pretty hard after 8 a.m.

Running Tips
1)    Ensure that your toenails are trimmed. Keep ready your race kit (t-shirt and shorts), hydration belt the previous night itself. 
2)    If you are prone to chafing, apply Vaseline/petroleum jelly wherever muscle rubs (nipples, inner thighs).
3)    Do not have anything unusual the night before the run. You might like to have something very light like a banana or a slice of bread about 1 hour before the run.
4)    Please ensure to do dynamic stretch before and after the run. Our physio will be leading a warm up and cool down sessions. Post run walk for a while and do static stretches to relax your muscles. 
5)    Line yourself according to your estimated finishing time. Faster runners should line up in front and slower runners, joggers/ walkers should take their place at the back. 
6)    Do not sprint. Pace yourself comfortably. You should be able to carry on a conversation while running.
7)    Do not obstruct the runners behind you. If you choose to slow down/ walk, move to the left of the trail, giving way for the faster runners to overtake you.
8)    Hydrate yourself well but do not over-hydrate. Do not gulp too much water all at once. Consume water sip by sip, just enough to replenish lost fluids. Along with water, also have some solids (biscuits/ bananas) and/ or electrolyte.
9)    Listen to your body. If for any reason you feel you cannot continue, there is no shame in throwing the towel. Please walk slowly to the nearest refreshment point and inform our volunteers that you need assistance. We have ambulance and Doctors in case of emergency separately for adults and kids. 
10) Don't throw paper cups inside the dam / greenery. Use the waste bins kept near the refreshment points. If required, put reflective tape on your running gear. 
11) Study the course so you know what to expect. Where are the turns, uphills, downhills or flats? How many aid stations? Where are they located?

12) Go to bed early. If you're nervous about waking up in the morning, set multiple alarms
