Hey there! I am an amateur trekker and if you are too and you still plan on going trekking, you should read along. :D
To begin with, Lohgad is an easy trek. It lies at 1033m above sea level. It may not be too high but it certainly is a lon walk once at the top. If you are a fairly fit person (if you workout atleast 2 times a week or are slightly active then I'll call you fairly fit!), this trek will be a cake-walk for you, provided you carry the right stuff with you.
Let's talk about what you should carry with you: Atleast 2 litres of water, lunch, windcheater and comfortable footwear. These are the basic things you need. Avoid wearing shoes and socks that will retain water because these take forever to dry and you don't want to be stuck with having cold feet till you reach home.
