Cross-train
The fitter you get, the better your tolerance will be to cold weather running because your capacity to perform will have increased and that will generate more heat. However, if you are truly sick of the cold the cross-training options are plentiful. You could run on a treadmill, swim, cycle, stair climb, the list goes on. To roughly work out the running equivalent of the exercise you choose, divide the time spent cross-training by the pace you would have run at the same effort level. For example, 30 minutes of cross-training is equal to about three miles at 10 minutes per mile running. It is important to remember that it is indeed possible to continue your outdoor running throughout the cold winter months and this is the best training for the race.
